The throttle is either leaking or just cracked enough to blow out of the relief valves but to not close them. Probably just leaking.

That is a 2-6-2. Not a 4-6-2.

I see he's attached to his train and just "oiling around".   Soon to depart.

It's common practice at such times to set the independent brake, open the cylinder cocks, set the valve motion to full forward or reverse, and crack the throttle a tiny bit to allow a trickel of steam to keep the cylinders warm.  This eliminates most of the amount of condensation in the cylinders.  Severe condensation could potentially damage the cyliinders and/or valve gear when starting, and will certainly rain down a filthy black rain upon surroundings, nearby people and passengers for the first several turns of the drivers when starting a train.

Larry, correct. But to do that you need enough steam to close the relief valves, to get the steam down to the cylinders. This doesn’t appear to be the case.
