K Line K3380-3876 TMCC

PSU - Have you lubed it?  As even if you say it's 'new' any K-Line engine has been sitting for several years now.

Good Luck!

The legacy remote defaults to Tmcc and cab1 mode.

Your K Line Loco should run just as it would under the old TMCC handheld.

It may be a matter of reducing the momentum setting. Pressing the L button on the bottom of the Legacy remote.

Or, finding the correct control setting.

You can choose between cab1, TMCC, and R100 ( relative 100 speed steps)

This topic has come up before and I forget which speed step setting is best. Possibly R100?

Worst case, try it with each speed step setting to see which gives it the best response.

These are great looking ,running, and sounding engines. The puffer smoke unit is so good who needs a fan.

I dumped my Legacy remake because the gearbox began failing. These K Line versions do not use the fragile gearbox  design of the Legacy version.

I've seen a few KLINE k4s on the secondary market and been very tempted.

I have the same locomotive and it has the 128 speed step board. Sometimes it doesn't register every single one of the throttle wheel clicks so you can just continually spin it past what appears to be max throttle on the Legacy remote to get it up to speed. Eventually it'll get there. Personally, I don't mind doing this, but if you'd rather not keep spinning the throttle wheel forever maybe someone else can chime in for a potential fix!

Hi TrainDane3768,

Thanks for the information on this engine. I wasn’t sure if I should just keep spinning the red button. This is very helpful as I thought it may have been a bad board or something like that.

Interestingly enough, I just played with it again and used the boost and it took off so I am guessing this needs a lot of run way to get to a Scale speed.

I will take it to the NJ Hi-Railers and try it out there, more room and a much larger layout.

Thank you!

I thought mine might have had a bad board as well until I accidentally discovered that wasn't the case. Glad it helped!

Thanks, I tried your suggestions and it has gotten better but I can also upgrade the electronics which I may do. It has performed better based on the 2 suggestions.

More later when I run it at the NJHIRAILERS

Not familiar with the loco as such, but when it comes to speed steps I have always preferred 32, if you have a choice in the matter. I prefer the responsiveness, and it allows me to make the choice about  speeding up the loco slowly, or a bit more quickly.
