Plate 167:  Building a locomotive service yard, Part 33:  the terminal blocks that will be used in the point-motor wiring scheme
(This plate added OCT 2003)

The three screw-type 10-position terminal blocks in this picture are from Miniatronics. They are sold three to a package. The layout builder purchased these terminal blocks from the Walthers Terminal Hobby Shop.

These terminal blocks, and many more like them, will be installed within a concealed location somewhere in the layout. Wires from point motors, miniature lamp posts, railyard lights, building lights, and numerous other devices and lights will all be neatly gathered into terminal blocks like these. The matching wires that emerge from the terminal blocks will be bundled into one or more "cables" (a cable is simply a bunch of wires). The cables will then be run to a control center which will contain the power supplies and switch levers. Since the control center is cable-attached, it need not be rigidly fastened to the layout. Cable attachment provides the operator with the freedom to pick his own location for operating the layout, limited only by the length of the cables.
