It is late 1949 (it is always late 1949 here on the Pomfret Division), and a Pennsy merchandise consist is passing by on the mainline. The L2 is normally not used for this run, but the J1a had a failed bearing and went to the shop. Its been a long time since this 30 year old engine has gone this fast, and folks near the track swear they heard "Whee!" as the engine passed.
This is a K-Line engine upgraded with ERR cruise. The boxcar is MTH.
