It is a clear, cold morning and the little A5, affectionately known as the "Tweet" due to its high pitched whistle, is taking some empty cars to the docks. The little shifter was the only engine that could negotiate the tight turns on the city's streets. Unfortunately, this is late 1949 and Tweet will soon be replaced by Pennsy's new 44 ton diesels.
This is K-line's TMCC version of the model upgraded with cruise and 4 cuffs/revolution.
