Thanks guys.
The hoppers shown were decorated for a customer, not mine.
I have no interest in the line past the mid 70’s. When the B&O’s 8 SIRT AlCo S-2’s all left the Island for Ohio and the MTA moved in, it was all over with. Most of the freight sidings were removed including the S.I. Advance. Not much interest in these non-historical times. At least the Grasmere re-built siding and viaducts are still in place.
I almost had to ask, what is an 821, LOL!
