The Operating Watchman No. 1047 was most likely only manufactured in 1959, but due to lax sales it was carried over for an additional two years.
Produced on a painted GREEN metal base, Lionel would add additional plastic details to the top. The watchman waves his flag as the train approches and was made out of DARK BLUE painted plastic with FLESH colored hands and face. Two binding posts connect this accessory to an No. 145C contact that triggered the watchman by the weight of the train.
This is a difficult piece to find. There are no variations.
