The RealTrax Catenary System is designed to
enhance the realism of electric locomotives. Your
M.T.H. GG-1, Cascade, or other electrics will look
far more realistic when its pantographs are
contacting the overhead wire. For even more
authenticity, you can power the catenary and run
your engines via the overhead wires rather than the
center rail.
The enclosed instructions and guidelines will tell
you how to connect and power the catenary and
give suggestions how you can make it fit your own
layout for the best effect.

Page 4: Guidelines For Fitting To A Layout
Guidelines for Fitting to a Layout While the catenary system is easy to assemble and adjust, you will need to determine for yourself how it will best fit your layout and engines. Because there are so many variations in layouts and engines, it is impossible for us to give detailed plan measurements, but we do have some rules of thumb that will make outfitting your layout with the catenary system much easier. - Page 5 Be sure to connect the power pole to a straight section of track to avoid potential overhang problems as a large engine or car rounds a curve. If you plan to continue to run via track power exclusively, you can remove the lock- on and treat that pole like all the non-power poles.
- Page 6 The metal messenger wires should be bent to help them follow the curves of your layout, and the messenger brace can be adjusted on the messenger arm, from the end to the point where it meets the arm support, to help align the overhead wires with the track.

Page 7: Set-Up
Set-Up Once you have carefully planned the location of the power and non-power poles, you can begin installation. Powering the layout: There are three ways you can use the power pole to power engines via the catenary system. 1. To use the power pole and its lock-on connection to power RealTrax as well as the catenary: Check the lock-on portion of the base to make sure the small metal hooks in the back are seated at the top of the lock-on (not bent down), then slide the... - Page 8 parallel with the track edge and screw it firmly brackets on both sides of the base. 2. To allow the catenary to share existing RealTrax track power from an existing RealTrax lock-on: Check the lock-on portion of the base to make sure the small metal hooks in Connect the red wire from the transformer (+) the back are seated at the top of the lock-on (not bent down), then slide the back of the lock-on into the pole base.
- Page 9 To affix an non-power pole to your layout: Mount the non-power pole far enough from track to adjust messenger brace in either direction (as shown on the previous page) over track as needed (see "To adjust messenger brace" section below). You can use the power pole as a non-power pole if you choose.
- Page 10 To adjust messenger arm height: With the pole and wire installed and the engine(s) you will most often run on the track, fix the optimal height of the messenger arm by tightening messenger arm set screw. Make sure the wires will push down slightly on the pantographs to ensure steady contact.
- Page 11 whether the wire is already curved enough to follow your trac If so, determine which direction and distance the wire needs To adjust messenger brace: maintain smooth contact with the engine's pantograph. Moving the engine slowly along the track, check to see where the pantograph loses contact with the messenger wire.

Powering the Engine Through the Catenary If you are using the power lock-on, the catenary system is powered and ready to run your engines. Your engines, however, may need adjustment to prepare them to accept power via their pantographs. ® To connect the pantograph to the positive power circuit of an M.T.H. -

Maintenance Cleaning the messenger wires: With the transformer turned off, occasionally wipe the underside of the messenger wire with a rag and denatured alcohol. Troubleshooting Although this catenary system has been designed and engineered for ease of use, you may have some questions during initial set-up and operation.
