As far as getting into the cab windows... many years ago I was a volunteer on a local tourist railroad. We ran on the tracks of a shortline freight railroad and occasionally used their power when our steam locomotive wasn’t operating. I recall one instance where we were given permission to use their engine, an ex-Conrail GP10. The freight crew had locked the cab doors and we couldn’t reach anyone to come and unlock it. One door was padlocked and the other locked from the inside. So...
One of our volunteers managed to push back the side windows (they were latched together but slid in their tracks) with a broomstick from the walkway, and climbed around into the cab through the window. Dumb move as if he had fallen, it’s quite a drop from the cab to the ground...
