Good Morning All,
Going back in the discussion a bit, there are six active customers on the Fitchburg Secondary. From south to north -
Safety Kleen (a pair of tanks) - Marlboro Jct, generally switched twice a week (Tues & Thurs)
Ken's Foods (tanks and hoppers) - Marlboro, generally gets 3 switches a week (I've mostly seen Tu-Thurs-Fri)
NewCorr Packaging (up to 5 boxcars) - Northboro, generally twice a week (Tues & Thurs). This used to be a Toys R Us warehouse back in the day.
There are no active customers between Northboro and Lancaster. The last Clinton customer, Reiser scrap on the Lancaster IT, closed up a few years ago
Culpepper Lumber (formerly Bestway, centerbeams) - Lancaster, generally switched M-W-F, sometimes less outside construction season
WinWaste (formerly UMM, C&D gons) - Leominster trash customer, generally M-W-F
Teknor Apex (typically 1 tank and 1 hopper)- Leominster, switched once a week, generally either on Mon or Wed.
Obviously things can change with customer needs and the railroad's ability to perform. The Secondary is designated 'other than main track' so it's all 10 (a far cry from the 25 of the recent past).
On Leominster days they'll run up to the small yard, run around the train and head back south.
