These suckers were brand new and I put the DCC in before they even ran on my DC track. They were for use at my club which is a DCC Super Chief.
Anyway, I just tried running the A and B unites together, but not connected. The B unit is twice as fast as the A. I’m going to call Lifelike and see if I can get them fixed. these are supposed to be good quality Locmotives and I have not seen it.
I think the speed problem is a problem with the decoder. And even if it is the engine, you can easily fix the problem with a little programming. Compare your speed tables on the two engines. If they are not the same. Make them the same. If they are the same and the engines still dont run together, set the faster engine to go slower than the slower engine on a given speed step. This is most easily done with a computer and a cable to connect it to your command station being that each speed step is it’s own CV and there are 128 of them, but it can be done without the computer if you have lots of spare time
The speed difference is without the decoders–just the DC circuit boards.
OK, but you can play with the programming on the decoders and make them run together.
That would be an option, I agree. When I first read it, it seemed like a great idea. But I haven’t had both decoders working yet. Right now neither works. The A unit has some sort of noise denoting friction bad enough to make it run at half the speed of the B unit. For new equipment, it falls short of what I’d expect from Proto 2000.
