Horn Control in TMCC Lashup

Only the front should blow. Just like in a TMCC MU. 

Keith,

I suspect we'll get an answer once gunrunnerjohn reads this.

MartyE -  That is the I understand it, what I am looking for is a work-around to get 'er to blow.

Reverse the motor leads and give it the same ID and run them as an engine. That would be my only solution. Only later Legacy engines can do what you are looking to do. 

U can enter eng 99 and that might work or it does on Legacy engines. All the horns will blow, don't know if it works on Atlas. TRAIN NERD AL

MartyE - I did that many years ago with some Weaver GP-9s.  It was not an issue at the time since only the lead unit had sound.

Al -  Just to be clear, should I enter eng #99 for the backwards running unit?

99 is for later Legacy engines only. And it is an engine function only. 

Thanks MartyE,  these units were made in 2005 or 06.

MartyE is probably correct cause it doesn't work on all my engines.   AL

It doesn't even work for all Legacy engines.  That was cut in several years after Legacy hit the market, around the 2010 timeframe.  My 2009 Lionmaster SD-80 does not react to 99.

I think I may have just figured it out.  I will program the "backwards" running unit as a single engine lashup to start in reverse.  Then add my other engines to front and run the train not as a semi-lashup mode by assinging the same engine number to both powered units.  The "backwards" unit should retain its starting in reverse features.

What say you?
