As stated in another post, LOSA/SALO and DOBO/BODO are the ONLY
freights (except a rare extra) to pass through Winchester on the T's
Lowell mainline.
LOSA/SALO - On duty 7PM at Lowell and runs via Wamesit/Lowell Jct to
Lawrence to get its train. Runs to Boston from Lawrence via the Wildcat
Branch and the Lowell main. Switches all customers between Wilmington
and Winchester usually on its southbound trip. Rarely, if ever, goes to
Salem. SALO goes straight to Lowell (unless otherwise redirected) right
up the T's mainline just prior to the AM rush hour parade. Runs Monday
through Friday and occasionally on Sunday.
DOBO/BODO - On duty 7PM Dover and comes directly to Boston via the
Wildcat Branch and Lowell mainline. On RARE occasions, BODO will run
out the Reading/Haverhill mainline, but this is not the desired way to go
home due to the slowness of the Western Route mainline and noise issues.
DOBO will only come down the Reading line if forced to. Again, the
aforementioned issues apply as they do for BODO. HOWEVER, it is NO
joy handling a loaded sand/gravel train down into the tunnel at Wellington,
then up over the Mystic River and down again to Reading Jct in
Somerville.
CSX does not run or have rights or reasons to run north of Somerville.
FYI - LO-1 runs Monday through Firday between Lowell and Billerica
Shop in daylight. Usually heads back to Lowell after 2-3PM.
