Has anyone successfully "Lashed-up" a K-Line and Lionel K-4 Pacific?

Set the stall speeds on both engines so they start to move at the same time when the throttle is first moved. Also, what you are trying to do is "Double Head" not Lash-up.

I'm surprised by that, have you tried changing the speed steps to M or H on the legacy k-4. Legacy locos even operated under TMCC typically start off at signifigantly slower speeds than TMCC locos. Regardless, they probably will not "lashup" well no matter what, as they're electronics are entirely different.

.......or MU

To my mind, the most important part of a multiple unit locomotive is making sure the mechanics of the drive trains are identical, or at least exceptionally similar.

The fancy electronics (do I sound like a geezer, or what?) can only do so much to match the systems. If they have dissimilar motors, or gear ratios, or wheel sizes, it's not gonna work well.

A good way to tell how closely they are matched is to run them close to each other in a conventional environment.

No, wait.

That would not account for some of the conventional speed control systems out there, K-Line's house brand, MTH's PS2 when operated in conventional mode.

You can always give it a try. Some of the cruise control systems allow you to adjust one locomotive. ERR has the "exclusive nudge feature" if I recall the advertising correctly, and Lionel probably already has it as well.

On the other hand, could it just be the K-Line speed control?

This is the Lionel loco that is reputed to have its ancestry in the K-Line scale K-4, right?

That would lead one to think that the mechanisms should be similar, if not as close to identical as current manufacturing process deliver.

I wonder it the motor is the same. Is anyone willing to pop the hood and check out the differences between the Lionel and the K-Line?

Maybe shut off cruise on the units since the K-line cruise and Legacy probably would'nt get along.

No RickO, you're wrong. Diesels and Electrics MU by way of MU Hoses and Cables. Correct me if I'm wrong, But Steam still uses an engineer in each Locomotive to control the Locomotive. No MU hoses or cables on steam.

Also, he is not using Legacy. I believe he said he was using TMCC, so I would believe with no way to load the Legacy Module the K-4 would be set for TMCC and I have been able to run alot of different locos by matching the stall speed. I would also turn off speed control if they both don't have it.

I assure you, I know that. Just using Lionel's incorrect terminology.

I thought about setting the stall speed as suggested, but thought I would try to draw on someone's experience before investing a lot of time in the effort.

Thanks for all the replies so far.

I stand corrected!

Understood, I have the new k-4 and run it with the old tmcc,set at M- 100 speed steps, it basically begins to crawl from a stand still, I don't see any way possible that it would run faster than a much older TMCC equipped loco. Older TMCC locos typically start at a higher speed like say 5mph or so.

I have the K-Line PRR Mikado and it starts off just as slow as my Lionel K-4 with Legacy.

Interesting, obviously k lines drive train is the major factor in the legacy versions performance,do miss k line, what great o-guage products!

Oh yeah! Ask Rich M. and Hotwater. I believe Rich M installed an MU box on the 765 OH... Ricko!

You need to set the tmcc engine as the lead even if you are only running in a tmcc enviroment.

I'm pretty sure you have to turn the cruise off.
