interlocking plant modeling

Model Railroader Prototype information for the modeler

I am finally getting around to putting the lever plant inside my kitbashed Big Four interlocking tower built on stilts. This is a modernized interlocking plant with electric switch machines and signals rather than the ones operated by piping. I am trying to figure out how much of the original lever plant they used when they modernized with the electric switch motors and signals. After buying a nice laser kit for the levers I need to know how much of the pipeing they left in place as on these CCC&Stl towers everything is visible.

Thanks for any help you may be able to provide

Most of the ‘modernized’ Armstrong plants I have seen had the actual ‘locking bed’ just under the levers, and the electrical contactors/relays were in the lower(first floor) of the tower. Since this one you describe is on ‘stilts’, I would suspect some kind of instrument house under the tower or nearby.

In the Jan. 2004 issue of Model Railroader there is a excellent article on interlocking plants and there modeling. I found my issue on e-bay.
