What is this on this B&LE cab?

Could that be a valve key, where the valve is located either deep down, or high above.

BUT, if for water, wouldn't it be more convenient on a tender?

It's more likely a pole used to close the angle cock on the car immediately ahead of the caboose on a moving train (notice the loop on the bottom end of the pole), so the caboose can cut away on the fly without throwing the train into emergency.

Thank you Mark.

That makes sense.

I really am not familiar with prototype railroading to know, but thanks to you I now know.

Take Care,

Ralph

Consistent with the chain going to the cut lever to uncouple from the platform.

Or it could be a drawing someone made on the photo.  The loop at the bottom is likely the handle for the uncoupling lever.

Or not...

Mark,

You are correct.  It is a tool to close the angle cock.

Here is a photo of one.

We've used these on Union Railroad cabeese as well.

Mark,

Do you still work for the URR?

Dave

Thanks to all. I will include it on the model. Malcolm

A complet detailed caboose, created by Malcolm.

Even the tool is included in the detailing, that's great of you Malcolm.

Take Care,

Dave,

Yes, still working for the 'U'.
