The Tyco 4 wheel Birney trolley from the mid 60s followed by the AHM 4-4-0 Genoa ran around my Christmas tree all thru my childhood and would have to be credited with being the ones to intraduce to the hobby. Sadly, these aren't the originals, the trolley having succumbed to the rigors of playground fun and the Genoa the victim of many of my hobby firsts including weathering and redetailing. I don't know its fate after 1978 as it was over a friend's house on his layout then. The Athearn Hustler was my first locomotive purchase when I stepped over from N to HO in 1992. Extensively redetailed, remotored and DCC equipped, it is the classic example of the 100 year old ax that's had it's head replaced 4 times and its handle 3 times. The juicejack was my first loco scratchbuild and, at the behest of my beloved, will never see a coat of paint.
