A/C on train compartments

[IceMan08]

Hi guys, I was wondering whether any of you had experience with A/C on trains in the uk? basically we have been asked to tender for the removal of the existing system for it to be sent off and refurbed and re-install on its return, I have never worked on trains so I am looking for an approximate time involved in removing one of the said systems, also an approximate quantity of refrig in each system. Thanks for your help in advance!

AC systems on trains in Belgium and Sweden are installed on skids placed in the double roof of train carriages.
In order to be able to remove them, you would need a 4 to 5 meters high adjustable deck and a crane of appropriate load capability.

Not saying that this is what you will be getting but might show you something similar, downloadable brochure have some tech details in them.

You must check on the tender what systems you would be working on some might be air cycle systems with bootstrap turbo's ?
