Important DC Advisory

Do NOT use cheaper "train-set"-type controllers with any of your Rapido locomotives. Several models of controller are notorious for voltage spikes and they WILL destroy your locomotive. There is no “if” about it. We will try to help you if we have the parts, but we are not responsible for locomotive damage due to voltage spikes in your power supply. As well, we will not repair any Rapido locomotive damaged by any "train-set"-type DC controller unless you have retired the controller. Otherwise the damage will likely reoccur. “Train-set”-type DC controllers should not be used with any modern model locomotives.

Function Issues on Digitrax Systems

If you operate with a Digitrax DCC system and your DCC loco does not seem to be responding as it should, please try the fix described below before contacting us. It may save you some time and aggravation!

Apparently, some Digitrax systems store the address of every single loco that they've ever used on them, and regardless of whether the loco was dispatched or not. Once this memory fills up, any new locos that attempt to be used by that system exhibit very unusual behavior including non-working functions and odd responses.

The solution to this is easy. All you need to do is clear the memory in your system. This is done by clearing slot #36, see the instructions below. Once you've done this, you'll likely find that your loco operates exactly as you expected it should.

General Instructions for Closing Command Station Option Switches (for specific instructions for your command station and throttle, see the instruction manual for your equipment):

  • On the command station, set the MODE toggle switch to the OP (center) position.
  • Using your throttle go into Switch Mode
  • Enter the Option Switch number you wish to change (in this case 36).
  • Press the “c” key on the throttle.
  • You will hear a beep.
  • On the command station move the MODE toggle down to SLEEP then back up to RUN.
  • Using your throttle, turn Track Status back on.

A small number of users have reported that their Amtrak F40PHs were derailing on curves. The following solution should fix the issue. The speed recorder, located on the engineer’s side of the front truck, runs from the truck up into the chassis. In some circumstances, the “cable” section of the part is too long and the top snags on the top of the chassis, which limits the movement of the locomotive’s front truck. To remedy this, remove the locomotive’s shell by first removing the couplers and coupler boxes before gently lifting the shell off the chassis. Trace the recorder “cable” from the truck up into the chassis. You may see the end of the part bent back on itself and wedged in the channel cut into the chassis to accommodate it. Carefully trim off the top portion of the speed recorder “cable” so that the truck rotates more freely. Test the locomotive and, if all is well, replace the shell and the couplers. If you require additional assistance, please contact us.
