Martinazzi Tualatin, Oregon 97062 Re: Portland & Western Railroad/Union Pacific Railroad Connection Study W&H Pacific Job No: 0130-1001 Dear Mike: Attached is the results of the study to evaluate the feasibility of up to five alternative railroad routes to connect the Portland& Western Railroad, Inc. (P&W)with the Union Pacific Railroad Company(UP) in Tualatin. Of the five alternative routes provided by the City,two of the routes satisfy the design, operating and safety criteria that we established at the outset of the study or are otherwise acceptable to the P&W. One alternative varies from the criteria,a,but could be considered by the P&W since it is expected to have one of the lowest construction costs. A fourth alternative varies from the design and operational criteria and is considered marginal, and the fifth is not feasible because it will not satisfy the required criteria. After you review this report,we will talk further about the most suitable presentation graphic for you to resent the results to the Ci Council. �P Y P City . We have enjoyed the opportunity to work with you and the railroad, and would be pleased to provide assistance as the City moves forward with the next step.

These routes were identified by the City to connect the Portland & Western Railroad, Inc. (P&W) main track(former Burlington Northern Sante Fe Main Track) with the Union Pacific Railroad Company(UP)Main Track(under 20-year lease to the P&W). This study was intended to provide a recommended route or routes to complete this connection to allow abandonment of a portion of the existing P&W trackage in Tualatin for other uses. A preferred route must satisfy the design and operating requirements of the P&W and the safety requirements of the Safety Section of the Oregon Department of Transportation(ODOT). Limited horizontal,vertical and topographic data was available for this evaluation. The results of the study are based on interpretation and interpolation of these data from GIS mapping, supplemented by an aerial photograph dated July 20, 1997, and by observations made during a driving/walking reconnaissance of the route locations. The alignments shown on the attached map exhibit are accurate and detailed only to the extent necessary to determine the general feasibility of each alternative and to make relative comparisons of the alternatives. EVALUATION CRITERIA The railroad design and operating criteria used in the development of the study was established at a meeting at the City of Tualatin offices on December 29, 1997, attended by Michael A. McKillip of the City of Tualatin; Robert I.Melbo, Charles R. Gilbert, and Bruce Carswell of the P&W; and Gregory K. Gifford and Wayne L. Stanley of W&H Pacific, Inc. The following criteria was used as the basis for the evaluation presented in this report: • 1.2% ruling grade, 1.0% desirable; curves compensated at a rate of 0.04%per degree of curve • Rate of change for vertical curves is 0.1%per station in sags and 0.2%per station on crests • Class 4 operations (60 mph for passenger trains; 40 mph for freight trains) • 25 mph on east(Portland) side of wye connections; 10 mph on west side of wye connections • Number 14 turnouts • Nine-degree to 10 degree curves are acceptable,particularly on wyes,with flatter curves if possible at other locations • Roadbed top width shall be 26 feet(13-foot half-width) • Embankments and excavations for track roadbeds shall be constructed with side slopes having a ratio of 2 horizontal to 1 vertical • Toe ditches shall be provided for drainage • Trestles were suggested as the means for mitigating encroachment on wetland areas •, Right-of-way width shall be 60 feet(30-foot half-width)with slope easements if more than 60 feet required because of slope encroachments. • Track material shall be 136 pound RE rail, and other track material, 7"x 9"x 9'-0"treated wood crossties spaced at 18-inches in at-grade road crossings and 21-%i inches in open track. • The track ballast section shall consist of 8-inches of No. 4 American Railway Engineering and Maintenance Association(AREMA)ballast beneath the crossties on 12-inches of subballast(e.g., ODOT base aggregate) • At-grade track crossings of roadways are to be as close to perpendicular as possible and shall utilize OMNI improved concrete panels • At-grade track crossings shall be protected, where appropriate,by flashing light signals having automatic gate anus CONNECTION ROUTE DESCRIPTIONS Alternative A This route diverges northerly from the P&W Main Track south of S.W. Tonquin Road through a No. 14 turnout split to accommodate continued access to a portion of the Main Track that will remain as a lead to S.W. 89`h Avenue to provide rail service to some industrial spur tracks. The horizontal alignment turns northwesterly across land which is part of a Morse Brothers planned expansion through a 2°15' curve and continues on the northerly side of a high-voltage power line right-of-way across S.W. Dahlke Lane, S.W. Oregon Street, and S.W. Tualatin- Sherwood Road and proceeds to the UP Railroad Main Track at a point just east of the intersection of the UP with S.W. Tualatin-Sherwood Road,where a wye connection is made through No. 14 turnouts and 10° curves. The No. 14 turnout in the UP Main Track on the west leg of the wye will be located on the west side of the UP and S.W. Tualatin-Sherwood Road intersection, creating an additional grade crossing, in order to keep the turnout connecting the west leg of the wye with the UP Main Track. The horizontal alignment will provide for 60 mph passenger and 40 mph freight train operations, except the wyes,where 35 mph and 25 mph operations are possible on the east leg of the wye connection and 20 mph and 10 mph are possible on the west leg of the wye. The length of this route between the P&W Main Track and the UP Main Track including the east leg of the wye is approximately 11, 900 feet. The length of the west leg of the wye is approximately 1,280 feet. The differences in elevation and the horizontal distance between the P&W Main Track and S.W. Oregon Street result in a-1.51%grade being required to provide grade crossings at S.W. Oregon Street and S.W. Tualatin-Sherwood Road. It will not, however,be possible to provide the required vertical curves and achieve less than a 4%to 5% grade in the horizontal distance available between S.W. Oregon Street and the UP Main Track. Therefore, it is not feasible to provide a connection that includes grade crossings of both S.W. Oregon Street and S.W. Tualatin-Sherwood Road. A connection is possible along this horizontal alignment, utilizing approximately 8,500 feet (1.61mi.) of-1.89% grade from the P&W Main Track to a grade separation carrying the rail connection under S.W. Oregon Street and a+0.47% grade from S.W. Oregon Street across S.W. Tualatin-Sherwood Road to the UP Main Track. Some minor adjustments of the S.W. Tualatin-Sherwood Road profile may be required to provide a smooth match with the track. A grade crossing will also be created at S.W. Tonquin Road and S.W. Dahlke Lane. 2 This alternative would require variance from the design grade criteria that may result in an increase in the motive power requirements for train operations. The route will go directly through an area of planned expansion by Morse Brothers and three to four industrial/commercial businesses in the northeast quadrant of the S.W. Tualatin-Sherwood Road intersection with the UP Main Track. Two of the buildings displaced are relatively new facilities housing automotive related enterprises (transmission repair shop) and third is a combination storage and office housing a forest products business. It appears that up to six residential and/or residential out buildings and an industrial/commercial building will be displaced by the route between the P&W Main Track and S.W. Oregon Street. The estimated construction cost for the Alternative A is S 26,900,000, including right-of-way acquisition and displacement of homes and industrial/commercial buildings. This is the highest cost alternative. Alternative B This route diverges northerly from the P&W Main Track north of S.W. Tonquin Road near S.W. 1st Street through a No. 14 turnout split to accommodate continued access to a portion of the Main Track that will remain in place as a lead to near S.W. 891'Avenue to provide rail service to some industrial spur tracks. The route continues horizontally north and slightly west through a 2° 15' curve to the left and then a 20 15' curve to the right and crosses S.W. Tualatin-Sherwood Road approximately at the southerly projection of S.W. 124 'Avenue,continues northerly on the east side of S.W. 124`h Avenue and proceeds to the UP Main Track on the south side of S.W. Herman Road, where a wye connection is made through No. 14 turnouts and 10°curves. The west lei of the wye connection will create a grade crossing of an unimproved portion of S.W. 124 Avenue. The horizontal alignment will provide for 60 mph passenger and 40 mph freight train operation, except at the wye, where 35 mph passenger and 25 mph freight train operations are possible on the east leg of the wye and 20 mph passenger and 10 mph freight train operations are possible on the west leg of the wye connection. The length of the route from the P&W Main Track to the UP Main Track including the east leg of the wye, is 10,725 feet. The length of the west leg of the wye is approximately 2,100 feet. A-0.79% grade between the P&W Main Track and S.W. Tualatin-Sherwood Road will provide a grade crossing at S.W. Tualatin-Sherwood. It is not possible to provide a grade of even 2.5% to 3.0% and provide the required vertical curves to provide an acceptable grade between S.W. Tualatin-Sherwood Road and the UP Main Track. It is possible,however, to provide a vertical alignment for a grade separation carrying the railroad under S.W. Tualatin-Sherwood Road with approximately 5,500 feet of-1.37 % grade from the P&W Main Track to S.W. Tualatin- Sherwood Road and a-0.98% grade from S.W. Tualatin-Sherwood Road to the UP Main Track. The route will create grade crossings at S.W. McCamant Drive in addition to the grade separation at S.W. Tualatin-Sherwood Road. A grade crossing will also be created by the west leg of the wye at S.W. 124 'Avenue if this street is improved southerly from its limits just south of the UP Main Track at S.W. Herman Road. 3 This route may result in additional motive power being required for train operations because of the variance from the design grade criteria. The east leg of this route has been oriented to the east and clear.of a corrugated metal-sided warehouse/shop building in the southeast quadrant of the UP Main Track and S.W. 124'h Avenue. The west leg of the wye has been shown longer than technically necessary to avoid contact with improvements on the Lumber Products Co. site at the southwest quadrant of the UP Main Track and S.W. 124`h Avenue. The estimated construction cost of Alternative B, including right-of-way acquisition, is $14,800,000. This is the second lowest cost alternative. Alternative C This route diverges northerly from the P&W Main Track of S.W. Tonquin Road near S.W. 1" Street at the same point as Alternate B through a No. 14 turnout split to accommodate continued access to a portion of the existing Main Track that will remain as a lead to near S.W. 890h Avenue to provide rail service to some industrial spur tracks. The horizontal alignment of this route turns directly north through a 2° 15' curve to the right and proceeds across S.W. McCamant Drive and crosses S.W. Tualatin-Sherwood Road about 3/8 miles west of the S.W. Tualatin-Sherwood Road/S.W. Avery Street intersection. The route continues directly north to the UP Main Track on the south side of S.W. Herman Road, where a wye connection is made through No. 14 turnouts and 10° curves. The horizontal alignment of this route will provide for 60 mph passenger and 40 mph freight train operations, except at the wye connection,where 35 mph passenger and 25 mph freight train operations are possible over the east leg of the wye and 20 mph passenger and 10 mph freight train operations are possible over the west leg off the wye. The length of this route between the P&W Main Track and the UP Main Track, including the east leg of the wye, is approximately 12,000 feet. The length of the west leg of the wye is approximately 1,515 feet. Approximately 5,700 feet of-1.2% grade from the P&W Main Track to S.W. Tualatin-Sherwood Road, Track results in a grade crossing at S.W. McCamant Road and S.W. Tualatin-Sherwood Road,with a level segment across S.W. Tualatin-Sherwood, and a-0.92% grade from S.W. Tualatin-Sherwood Road to the UP Main. This conforms to the vertical design criteria of the P&W Railroad. This alternative connection route should not require that additional motive power needs be considered above and beyond what is currently being utilized by the P&W. The west leg of the wye has been oriented to miss a concrete tilt-up moving and storage warehouse facility. The east leg of the wye will go to the east of two old structures, one a corrugated metal-sided building and the other a frame building, that were part of an onion packing operation. The line between S.W. Tualatin-Sherwood Road and the wye connection goes through, or at least in the proximity of, a storage area congested with truck trailers and some small wood frame yard offices. Insofar as it is possible to determine, it appears that the line will clear the small frame offices. The estimated construction cost of Alternative C, including right-of-way acquisition, is $21,300,000. This is the third lowest cost alternative. 4 Alternative D This route diverges northerly from the P&W Main Track just north of S.W. Avery Street through a No. 14 turnout split to accommodate continued access to a portion of the existing Main Track that will remain as a lead to near S.W. 89`h Avenue to provide rail service to some industrial spur tracks. The horizontal alignment turns to the left through a P curve and runs directly north approximately half-way between the southerly projection of S.W. 108`h Avenue and S.W. Teton Avenue across S.W. Tualatin-Sherwood Road and S.W. Manhasset Drive, turns slightly to the north northwest through a P curve to the left to mitigate the impact on some wetlands areas and continues to the UP Main Track on the south side of S.W. Herman Road where a Wye connection is made through No. 14 turnouts and 10° curves. The horizontal alignment of this route will provide for 35-mph passenger and 25 mph freight operations for all except the west leg of the wye, where 20-mph passenger and 10 mph freight operations are possible. The length of this route between the P&W Main Track and the UP Main Track, including the east leg of the wye, is approximately 4,985 feet. The length of the west leg of the wye is approximately 1,120 feet. The difference in elevation between the P&W Main Track and S.W. Tualatin-Sherwood Road is too great and the distance is too limited to provide an operational grade with the required vertical curves to construct a route with a grade crossing of S.W. Tualatin-Sherwood Road. It is possible to provide a-1.0%grade between the P&W Main Track and S.W. Tualatin- Sherwood Road approaching a new grade separation over the road. Once over the road, however, the difference in elevation is too great and the distance is too limited between the grade separation over S.W. Tualatin-Sherwood Road and the UP Main Track to provide operational grade with the required vertical curves. It is not technically possible to locate a route having an acceptable grade with either an at-grade or separated crossing of S.W. Tualatin-Sherwood Road. Therefore; this alternative is not considered feasible. The route would go through an industrial warehouse/office type building north of S.W. Manhasset Drive and both legs of an optimized wye alignment would go through a large area of pipe laydown storage near the UP Main Track along that portion of the route between S.W. Tualatin-Sherwood Road and the Main Track. Since this alternative is not feasible, no estimated construction cost was developed. Alternative E This route diverges from the P&W Main Track in a northeasterly direction through a No. 14 turnout split to accommodate continued access to a portion of the existing Main Track that will remain as a lead near S.W. 89`h Avenue to provide rail service to some industrial spur tracks. The horizontal alignment of this route turns slightly further to the north through a P curve to the left to proceed with an extremely oblique angle at-grade crossing of S.W. Tualatin-Sherwood 5 Road at S.W. 95`h Drive. The route then turns northerly through a 10° curve to the left and continues to the UP Railroad Main Track on the south side of S.W. Herman Road,where a wye connection is made through No. 14 turnouts and 10°curves. The horizontal alignment of this route will provide for 35-mph passenger and 25 mph freight train operations for all except the west leg of the wye, where 20-mph passenger and 10 mph freight operations are possible. The length of this route between the P&W Main Track and the UP Main Track, including the east leg of the wye, is approximately 5,870 feet. The length of the west leg of the wye is approximately 1,340 feet. The vertical difference in elevation and the distance between the P&W Main Track and S.W. Tualatin-Sherwood Road, as well as the acute crossing angle,will include approximately 750 feet of-2.0% grade(77.5 feet actual-2.%with remainder in transition between-2.% and-0.85% or-1.23%) from the P&W Main Track to north of S.W. Tualatin-Sherwood Road for a grade crossing of S.W. Tualatin-Sherwood Road. Representatives of the P&W have indicated this would be acceptable. The route continues on an approximately level grade to the UP Main Track from a point north of S.W. Tualatin-Sherwood Road. The undesirable safety aspects of the extremely acute grade crossing angle of S.W. Tualatin- Sherwood Road can be mitigated by flashing light signals with crossing gate arms to control vehicular traffic when trains are approaching and occupying the crossings. The impact on wetland areas between S.W. Tualatin-Sherwood Road can be mitigated by placing the tracks on a trestle-type bridge structure. The route sneaks between two industrial buildings, one on each side of S.W. Tualatin-Sherwood Road. If this route were selected for construction, a retaining wall should be considered in final design to reduce the impact of the embankment slope encroachment on the building north of the road. The west leg of the wye will displace one industrial type building on the south side of the UP Main Track and S.W. Herman Road. The east leg of the wye will cross S.W. 90`h Avenue. This crossing will be immediately contiguous to the existing UP crossing of S.W. 90`h Avenue and will be controlled by the existing flashing light signals with automatic gate arms. The estimated construction cost of Alternative E is$ 6,932,000, including right-of-way acquisition and the displacement of an industrial building. This alternative has the lowest estimated construction cost. CONCLUSIONS Alternatives C and E are technically feasible and meet the criteria establis ed for the study. Alternative B does not fully meet the criteria but could be feasible if it d s not impose unacceptable additional operating cost for the railroad. Alternative A al does not meet the criteria and should be considered further only if Alternatives B and C rove to be unacceptable after further evaluation. Alternative D does not meet the criteria and no mitigation has been identified. This alternative is considered not feasible. The relatively high estimated construction costs for Alternative E ($6,932,000), Alternative B ($14,800,000), Alternative C ($21,300,000), and Alternative A($26,900,000) are attributable mainly to extensive earthwork volumes and right-of-way acquisition. Since the depth of the excavations for the alternative routes are so great and will result in very wide excavation widths, 6 it has been assumed for the purpose of this study that slope easements for slopes outside the basic 60-foot right-of-way will not be acceptable and the entire width of the excavated areas will be purchased outright. RECOMMENDATIONS Alternative E is recommended as the preferred alternative since it is technically and operationally acceptable to the P&W Railroad and is anticipated to be the least cost. It meets all except the desired speed criteria established at the outset of the study. Alternative C is recommended as the second choice. Although it is anticipated to be more expensive than Alternative B, it satisfies the design and operational criteria completely. Alternative B is recommended as third choice and Alternativ asurth choice. Neither fully meets the established criteria but could be reevaluated he Railroad if other alternatives prove to be unacceptable. Alternative D is not feasible ould not be considered further. 7 Portland & Western Railroad/Union Pacific Railroad Connection Study Alternative Route Comparison Matrix Alternative A Alternative B Alternative C Alternative D Alternative E Route Length 11,900 Ft. 10,725 Ft. 12,000 Ft. 4,985 Ft. 5,870 Ft.
