I just purchased a pair of these engines new, #44775 & 44776. The speeds that they run at are radically different, making it difficult to run lashed up.
What brand and model # decoders are in these?
What adjustments can I make to them using an NCE Power Cab system to smooth this out?
Please help,

Here's a link to Atlas N decoder applications:
U25B has a Lenz built decoder but expect no support from Lenz. Atlas didn't buy support with them and chooses to do their own support. I generally use the LEO63XF manual for Atlas decoders.
As David pointed out, they do have a programmable speed table. I would suggest first resetting both decoders by writing 33 to CV8. Unfortunately, that won't reset the speed table so you will have to go through one at a time. Resetting will turn the speed tables off in CV29. The manual does have the default speed step settings. I've seen a few new engines come through with other than default settings.

Thank you gentlemen. I think I'll just return these for decoder ready models that I can install adequate decoders in.
