Bachmann track with a walthers building

[BaltoOhioRRfan]

I'm working on building a walthers shop building for photo ops for projects, etc to use on my test track, however i want to beable to remove it after i'm done with the photos. the buiding has track slits in the floor...should i cut em out so the rails can come through or is there another way?

its got three bays inside

can supply photos of the floor if needed.
