Running multiple TMCC/ Legacy engines at the same speed

Address 99 only works on Legacy engines and only ones produced after 2010ish time frame.

Trying to get a TMCC engine to run at the same speed as a Legacy would be a challenge without individually adjusting them.

You may want to build a "lashup" with the locomotives to get the best chance of getting them to run at the same speed.

Thanks for the response. Much more complicated than DCS.

How so?

I haven't found it to be substantially different.  Same concept, slightly (but not massively) different means to getting there.

Not discussing Lash up.  With DCS ,  Select " all engines" and control all active engine at once. This is a very useful feature for displaying several engines on different tracks.

They both have their plus and minuses.  Neither is rocket science although in my experience, DCS can be harder to implement in bigger layouts but the New Jersey HiRailers had the opposite experience.

I was merely suggesting using the lashup functionality to control multiple engines all at once at the same speed per your request - they don't have to be physically be coupled to one another and can be on different tracks in the same command environment despite falling under lashup nomenclature.

Another alternative would be to program multiple engines to the same engine number with the lowest common denominator feature set. All the engines will then respond to commands sent to that engine number.

There is no universal TMCC/Legacy concept of "all active trains", but only the most stubborn can't work through the suggestions provided to get to the ultimate goal of running trains!

Excellent point.  That feature is clearly unique.

Really?  They're still fighting DCS issues, but Legacy is running fine.

My experience is that engines even the same manufacturer vary from engine to engine.  For example a steam engine and a diesel switcher, I could not get to run at the same speed, consistently.  Part of that is going to be driven by the grades on my layout  and then also what each engine is pulling as far as a consist.

I can get it pretty close but engines are all running independently.  I have blocks on my layout so that will also help ensure there are fewer chances of crashes.

Every time this subject comes up I seem to recall where DCS worked great out of the box and Legacy / TMCC was a problem.  I do know they did solve a lot of the issues.

I think the pendulum has swung in the other direction, they were fighting TIU issues when I was talking to Bob.  With the TMCC Amplifier and some wiring changes, I believe last time I was there that TMCC/Legacy was working pretty well all over the layout.  Obviously, someone like Ben could tell us what the current state of affairs is.

I have zero issues getting Legacy or DCS engines running at the same speed for an MU configuration.  Obviously, I'm only talking about factory stock and not an upgraded engine.  TMCC engines are more of a crap shoot, and mixing TMCC and Legacy is also likely to be somewhat dicey.  My one grade to the second level doesn't introduce any additional issues.

I'm obviously talking about command mode, I have no idea what happens in conventional mode.
