Hi - I'm aware that this is one of those questions Google image search should be able to answer, but in this case my keywords don't seem to be getting me the answers I'm looking for ... as ever, the hope is that my begging threads here will lead to something good to share with you in time. 

I'm contemplating an engine house somewhere on my layout, and I'm looking for a prototype. Except I'm not sure such a prototype exists.

After an enjoyable vacation to the Owens Valley and Sierra Nevada, I came back with about 100 pounds of dirt and gravel from the right of way of the old Carson & Colorado.  The Laws museum was kind enough to offer an out of the way section of the track to dig on. 

Do any manufacturers produce glass block windows that I can use for some brick buildings/warehouses? Or if no commercial options are available, does anyone have any scratch building techniques that I could use to make my own? My layout is an industrial switching layout, and I would like to include some glass block windows in order to vary the look a bit.

Good afternoon everyone. Question for the east coast modelers. What would you recommend for a mainline ballast color and secondary track ballast color. On my layout the tracks are so close it does get a little confusing so I want to start to add some paint on the cork for now then ballast the tracks. I have 2 mainline track and 2 tracks that go to and from the helix and/or freight yard. I will have a black ballast in the freight yards and sidings... I do model 90's to current, if that matters...Suggestions welcome!!
