I recently got back into model railroading and have an old MRC remote control transformer. I wired it on to a track and when I put a train on the track the train took off like a bat out of ****. I can't seem to control the speed with the remote. Can anyone give some advice how to correct this. Thanks.

Are you running Tmcc engines ?? I have the same MRC.transformer and run Tmcc . When I do not have the track power from the MRC control all the way up to full throttle..the engines take off at full speed for some reason. It is important to have full throttle power to the track.
How do you have it wired? It seems that this is designed for separate circuits. No common for everything. Here's some box photos from the auction site. 2 separate tracks and separate accessory circuits. 2=center rail 3=outside rail Track #1
and so on. Don't mix the commons or "cross the streams"-Ghost Busters.
Call MRC 732-255-2300
That's incorrect. The transformer states on the box in two locations 3, 4, 5, and 6 are all common. Check you hand held device, that could be the problem. Also only 2 location 1 and 8 are variable. The others deliver either 14 or 10 volts fixed.

While they may be common, can they be connected together?
Note that TR#1 is terminals #2 & #3 and TR#2 is #6 & #7 on. It doesn't say Nos. 1,2,6, & 5 connected to any one common.
The statement at the bottom introduces the confusing part "...Not for Use with common rail layouts"
Which lead me to conclude meaning separate commons as defined on the label and to suggest a call MRC for clarification and an answer.
I own this particular unit and only use a single connection for the ground. Terminal one and eight are variable utilizing the handheld. The others are fixed voltage. In total I have five wire connected to the rear of the box with no issues like those described. Work backwards checking all connections to diagnosis the problem. One question, did it work at any time in the past?
I own a number of these MRC transformers and they work great. All the commons can be connected together. Some other features are the ability to program the starting voltage, set momentum and braking plus if two controllers are set to the same track the voltage responds to the lower of the two settings. If the controller is unplugged the track output remains as set until the controller is reconnected.
I use these as a simple way to run Legacy and original AF on the same layout. The tethered handhelds control the AF. Park them in an isolated block, set the MRC handhelds to 14 to 16V and run the legacy/TMCC engines with the Cab 2.
The output is non-sinusoidal so AF engines with built in horns/whistles cannot be used, the built in whistle will sound constantly. The controllers also operate the American Models built in sounds.

Attach the center rail to terminal 1 and the outside rail to either 3,4,5 or 6. Plug in the handheld, select track one and turn it all the way down. I have learned these are not always as responsive as you would like. Place the loco on the track. Now turn the the transformer on keeping your hand on the on/off switch. If the loco jumps, immediately turn the transformer off. If you have a second handheld, try that on also. Beyond that I have nothing else to offer.
