Herb: All steam loco brakes require an operating cylinder*, whether steam, air pressure or vacuum. *Usually, but not always, situated near the trailing (rear) of the frames (chassis) where the cylinder piston rods can act directly, or via a crank lever, onto the brake rigging rod ends.
Yes Duane, obvious really, the 'windows' gave access to a tortilla toaster - probably a better flavour than anything from Taco Bell - but not as good as egg & bacon directly off a clean shovel on a coal burner.
I've never repaired nor crewed an oil burner but as I understand it the fuel is fed centrally into a modified grate design so access from either side wouldn't be required ?.
Until someone comes up with a more plausible explanation for the little cab windows, I'm sticking with burrito warming windows.
Something that I find fascinating is the cab on this locomotive, which sits on the median of a boulevard near the museum:.
I'm really glad that they haven't restored this one, as then I couldn't see some of the details of the cab construction:
When you look at a steam locomotive, they look substantial and sturdy. But the cab infrastructure itself is fairly delicate-the frame is clear grain, quarter sawn (pine?) attached with mortise and tenon joints with a few square nails. The corners are secured with wrought iron angle pieces. Since it has square nails, I'm reasonable certain that this is the original cab. I haven't spent much time researching them, but this loco is either #2, 4 or 5, built in 1886 or 1887 respectively. I suspect that loco #7, the well maintained one in the town park (1899) would have wire nails as that is about the time folks switched. Now I wished I'd taken more pics...seems like as good a reason as any to go back!
