Well-Hung Bags

Right about the bags being part of the numbers.
Cab side water bags were always hung on the engineers side, from the bracket which is used to hold the "stop" flag at a station or other stop. On the K-28's this would obscure most of the third number.
The bags would swing, front to back, and rubbed paint clean off the cab side after a while, where they made contact. The fireman's bag was usually hung somewhere on the deck or on the side of the tender on the left side near the gangway. I don't ever recall a fireman's bag on the side of the cab, probably because there is not a bracket like that over on that side. I think the "Stop" bracket is only under the engineers window, but I could be wrong about that.
