A couple weeks ago, I went to Strasburg and rode on the open air car's observation platform. There was a handle coming up through the floor by the railing. The Observation car in the museum had the same platform. What are these handles for?

with a handle. a gear and a pawl (what the little piece of metal engaging the gear is called), it sounds like it could be the remnants of a manual brake.

On open-platform observation cars, several things could be piped through the floor:

  • A handle to pull in order to release the latch on the trap door, which should spring part way up and can be raised and latched to provide access to the rear steps.
  • A branch pipe off of the train line to apply and release brakes during shoving movements where the obs is leading.  This would have a rotary valve on it.
  • A branch pipe off of the brake pipe with a simple 90-degree ball valve to apply emergency brakes.
  • A hand brake, which would have a large horizontal ratchet handle on it.
  • A branch pipe off of the brake pipe with a small air whistle and an operating valve (spring-loaded button or - more commonly - small handle on a ball valve).

All of this was at the discretion of the owning railroad.  If the car was formerly a business car, it is more likely to be well-equipped with these devices and they could be located inside or out on the platform.  If it was a true observation car, less temptation is likely to be displayed out in the open.

Just going from memory, that vertical shaft with a "flop-over" handle on it, down on the floor, generally above were the rear coupler area is; could be the remote shut-off for the the rear steam line valve. In most cases, railroads preferred that the very last steam train line valve be cracked-open a bit, so as to maintain steam flow through that last car. That is why you see photos & movies of trains in the winter, having a wisp of steam trailing out the rear steam conduit.

Definitely the hand brake. The handle would hinge up, allow the hand brake chain to be tightened, then hang back down. As the chain tightened, the ratchet at the base would hold the chain in place. To loosen, you turn the chain slightly, then kicked the release on the ratchet near the floor. If they were overtightened, then they are a bear to release (been there, done that).
