Roundhouse Steam Lines

Happy Memorial Day Everyone,

I'm sitting here plotting on the interior for my Chama Roundhouse and I have a few questions concerning steam lines in the roundhouse.

I haven't been able to find any photos showing how/where the steam lines were routed in the Chama Roundhouse, let alone any other D&RGW roundhouse. HOw did the D&RGW go about routing the piping?
-Was it a specific size of pipe?
-Was it routed to every stall or did they have a couple of tap off points where flex hose could be hooked up?

I am hoping that someone on the boards may have some reference photos that I could look off of to get a general idea.

On a side note, does anyone know if the piping is still installed in the Chama Roundhouse today? Or was it removed when the steam boiler was removed?

Thanks for the help everyone.
