There is nothing more fascinating than driving in a remote location and all of sudden you see a tower spring from the earth! These towers came in all shapes and sizes and the east coast designs were so different from the west and yet they functioned in the same way. I have tried to make a variety from all regions and all railroads in my line. The originals in my line so far, were constructed of wood, brick, stone, and concrete. They include interlocking, sand, water, coaling, and in between tracks. I am fascinated that these necessary structures were also so beautiful. The towers in my line are small enough to fit any layout. Towers add such drama and conversation. My line is so affordable you can buy two or more for the cost of one brass engine!
