I'm getting ready to do a board on board construction of my engine house.  It's a John Allen FSM kit that I'm plagiarising. 

My question is what base would be best for the model?  I'll have track going into and through it of course.  I was thinking that an engine house would most likely have concrete for a floor. I'm sure that wood was also used.

Since I yet to have laid a single track on the impending layout I can be flexible.

Thank you.

Bob,
It really depends on your era and location.   Backwoods and branchlines many times used wood floors but engine houses built after 1900 came to appreciate concrete floors.   If it is used to an extent for heavy maintenance work or rebuilds, definitely concrete.

Dave, thank you.  I should have been a little more specific.  My RR is Narrow Gauge, D&RGWish.  I say that since my engines are lettered D&RGW. I don't intend to actually model the D&RGW per se but use their engines and rolling stock.

I have some plaster casting mix so I suppose I could pour a foundation.  I'll need to put something along the track rail to protect against the setting mix.

You can use thin strips of styrene along the rails, just make sure the inside of the rails leave enough room for the wheel flanges, the outside not so important.
As I said, if it is the primary engine house, than concrete would be good but if it is to be a branch or backwoods one, than try using wood.
There's lots of builds done using wood floors here and on other forums.

Bob, this would make a great build thread.  Any interest in documenting the build for all of us?

Dave, thanks again.

Tommy, let me think about it.  I  may post some pictures as I go.  I haven't built a train structure in a number of years.  Normally I build large RC Scale planes.  So this might not be as cool as a number of other builds I see here.

If the engine house had a wood floor all but the most back wood shop would have used 6 x 6 standing on end. Doing the floor this way makes for a much harder surface so it would not be damaged as easy as using a plank floor. Plus they would not have to have all the sub framing needed to support a plank floor. They would dig out the floor area and then lay a sand base then start standing the 6x's on end. When the floor was done they would sweep sand over the top to fill all the gaps.

Rich, thanks.  My wifes uncle worked in a shop years ago that had the same type of floor.  Laying all those 6x6's on end however would be a pain me thinks lol.

I have seen both wood and concrete and both are worn pretty good. There was one that had both. You could not tell what depth the wood was but it must have been hefty because there was heavy shop tools everywhere. The engine house I am doing has a cocrete floor. I fromed the perimiter and poured the floor right up to the edge of the rails. This was done after seeing a prototype done that way. There was no concrete between the rails and you could see the ties. The dirt mix in between the rails was completely oil soaked and hard packed. It was as smooth as the concrete. If you do concrete don't forget the multitude of cracks and chips.

Clif thanks for that.

I've seen concrete floors with only the rails showing.  But your method sounds like a good way to go.  Pictures of the first completed framed side.
