4.10 Strategy 3 – Rail Spur to the NASB Strategy 3 considers the feasibility of providing a rail spur from the MaineDOT Rockland Branch Railroad into the NASB. The intent of the spur is to provide direct freight railroad access to the redeveloped NASB. The primary focus of this evaluation is to determine the most logical means and layout for connecting a rail spur to the NASB. South of Bath Road, numerous possible track layouts can be accommodated, pending Strategy 1 roadway layouts and final redevelopment plans for NASB facilities. Strategy 1 encompasses proposed roadways into the NASB property, which likely have implications for both layout and vertical placement of proposed tracks south of Bath Road. The existing elevation of the Rockland Branch Railroad is approximately 10 feet lower than the surface of the adjacent Bath Road. In both options, this renders grade separation – with the tracks passing beneath a proposed Bath Road overpass – more feasible than when Bath Road passes beneath the tracks. Two route options were developed for the spur, and each provides rail access to the NASB in proximity to Hangar No. 6. The two route options consider crossing Bath Road either at grade or via a grade separation where the rail spur crosses beneath Bath Road, resulting in a total of four rail-spur options. The primary difference between the two route options is the origination of the spur on the Rockland Branch Railroad and the route to Hangar No. 6 on the NASB. Conceptual cost estimates were developed to identify the capital infrastructure investment necessary to build each route option in either an at-grade or grade-separated condition beneath Bath Road. 4.10.1 Options 1 and 1A Options 1 and 1A begin approximately 200 feet east of the existing at-grade crossing of the Rockland Branch Railroad and Jordan Avenue (Figures 4-17 and 4-18). From the junction with the Rockland Branch Railroad, the rail spur proceeds east and then southeast, crossing Bath Road via either a grade-separated (Option 1) or at-grade (Option 1A) crossing. The rail spur continues in a southerly direction, terminating behind existing Hangar No. 6. The primary advantage of this route option is the direct access to the NASB core area, which minimizes the need for heavy site-clearing prior to construction. Option 1 offers ample length to reach the existing surface elevations on NASB property if the rail spur travels beneath Bath Road, as it would for a grade-separated crossing. Summary of Options 127
The primary challenge with Option 1 is the proximity of where it crosses Bath Road relative to a proposed T-intersection that is currently part of the Strategy 1 proposals. In Option 1, with a grade-separated crossing for the intersection of the rail spur and Bath Road, the rail spur crosses beneath Bath Road roughly halfway between Jordan Avenue and the proposed T-intersection, both of which are at-grade intersections. There appears to be limited distance along Bath Road to ramp up and down for the overpass before meeting grade for Jordan Avenue and the proposed T-intersection at-grade intersections on either end. Therefore, a grade-separated crossing for the intersection of the rail spur with Bath Road may be difficult to accommodate. Additional challenges for Options 1 and 1A include sharp-curvature geometry and a conflict with an existing airport taxiway on NASB property. An at-grade crossing of an airport taxiway is not practical; therefore, this issue must be resolved with further study by adjusting the track alignment and/or reconfiguring existing taxiways to avoid the spur. The cost estimate does not include any costs associated with reconfiguring the taxiways. 4.10.2 Options 2 and 2A The route for Options 2 and 2A begins approximately 1,300 feet east of the existing at-grade industry crossing leading to Dragon Cement (Figures 4-19 and 2-20). From its junction with the Rockland Branch Railroad, the rail spur proceeds east and then southeast, crossing Bath Road via either a grade-separated (Option 2) or at-grade (Option 2A) crossing. The rail spur continues in a southwesterly direction, paralleling the existing tree line adjacent to the NASB jetfuel tank-storage site and terminating behind existing Hangar No. 6. The primary advantage of Option 2 is the distance along Bath Road that is provided between the grade-separated crossing with the rail spur and the at-grade intersection of the roadway entrance to the existing Merrymeeting Plaza Shopping Center. This distance is ample and renders a grade-separated crossing between the rail spur and Bath Road more feasible than in Option 1. The primary challenge associated with Options 2 and 2A is the circuitous route that the proposed rail spur needs to access the NASB. Additional complications also may result from constructing the rail spur through undeveloped forest. Summary of Options 128
