I have been a model railroader for years and sometimes I wonder how the things that we see in old pictures really worked?
Here are two:
On some old photos of steam tenders, I have seen items referred to as re railers that are attached to the frame of the tender.
My question is: What are they re railing...is it a derailed wheel of the leading truck of the engine or a car it is hauling? How does this device work to accomodate the rerailing? Was it used often and does it still have any application today?
My second question has to do with mechanical bell ringing on a steam locomotive. I know of arrangements in which the bell seems to be activated by a cord to the cab, but on the large locomotives such as the Challengers and Big Boys, a bell ringing seems to be mechanical. Was the device that ran the mechanical bell ringer, steam, electrical or air driven?
While I am on a roll....what about the power to drive an automatic coal stoker on the large steamers?
Looking forwards to the answers,
