F-line to Dudley via Park wrote:Omnova's a chemical company, which would suggest tankers. As long as they don't need Plate F cars, switching them past a full-high won't be any problem. PAS would just have to drop the rest of the cars on the main before switching them over the station turnout.
If so, PAS may have inadvertently created an operations or dispatch problem assuming Omnova Solutions and the paper facility require switching on the same day.
Several presumptions in this possible scenario-1. Loads/MTs from Newark America, or whatever the name of the paper company served via spur just beyond Wachusett Station, currently insignificant, increase slightly. This switch and spur runs from the parallel main track into the paper facility. 2. Omnova Solutions, at least initially, expects several multi-car loads/MTs requiring switching. 3. The current N. Station-Fitchburg schedule, when extended to Wachusett, will have 17 arrivals and 17 departures starting at approximately 5AM through 2AM. Depending on the time of day it would be unusual for a commuter train not to occupy a portion of the track between the layover yard and Fitchburg Station, where it again enters a siding. 4. PanAm continues with daily EB/WB freight movements plus FI-1 local service. 5. PanAm will remain, for several more months, essentially a single track main line from Fitchburg to Gardner as track, roadbed and bridge renovations continue. While runaround is available to FI-1 in the immediate vicinity of Wachusett Station, doing so closes (at least temporarily) both main tracks. The alternative is to temporarily close the single track section beyond the layover yard or leave the train east of Wachusett and perform multiple run around movements, which close both main tracks.
The roadbed and track on the spur serving the paper company are in poor condition and it would be problematic for FI-1 to execute a reverse move while remaining coupled to cars destined for other customers in the paper company to clear the main. Somewhat similarly, any switching movement into or exiting Omnova Solutions must be accomplished very rapidly to clear both the station track and the main to eliminate any potential schedule disruption (in either direction) of commuter rail. Holding EB freight movements at Gardner or WB movements at East Fitchburg or Hill Yard in Ayer is counter-intuitive as doing so prevents PanAm from realizing potential improvement in operations in the 22+ track miles between Ayer and Gardner.
