APT-P Stone-Faiveley Pan - Box on the Front?

[RedgateModels]

Can anyone tell me the function of the equipment mounted on the front of the APT-P Stone-Faiveley pan? I'm trying to model it in 3D and although I'm getting there copying the Hornby 2020's version I'm not sure that all the details etc are correct. Knowing what it actually does will help me to build it I think.

 

If anyone has a photo showing it that would be a help too 😉

 

This is the closest I've found on-line, but again the pic is from the wrong side, so does not show the "box" in any detail

EDIT: is it a big solenoid that pulls up the pan?

 

Edit: I'm told it's a pneumatic actuator, still need more pics 🙂

Sometimes referred to as an "Air motor". It looks to be in a different position to the position used on AC locomotives.

The "air motor" is the cylinder used to raise a pantograph. On a loco, it sat on the roof and raised the pan through a linkage. APT-P had the issue that the pantograph didn't tilt, whereas the bodyshell did. Hence the air motor being fitted in an unusual location.
