Can you explain train las ups and why/when you would use it.
Thank you.
Running two or more command control trains on the same track means you are switching between engine numbers on the Cab2 (or DCS handheld; you can run them all at the same time) to individually control each train. When in lashup mode, you are running all the engines in the consist together at the same time. As stated above, lashup mode is used when you want more than one powered engine to pull a train.
Unlike TMCC engines, most Legacy engines will run at the same speed in a lashup making MU consists and double heading easy. However, before I would run two or more engines connected together in a lashup I would run them separately in lashup to make sure they run close to the same speed. If they run well together, hook them up and pull that long train.
I have found Legacy diesels in a MU consist work well in a lashup, less so for steam engines double headed. Not sure why, just an observation.
As noted above, some do not like the word lashup. I think it is perfectly acceptable to use when referring to the act of electronically connecting together multiple command control engines to build a MU or double headed consist. MTH and Lionel both use this terminology in their manuals and I believe some just confuse the issue for those new to command control. However, please use MU consist or double head when referring to running the trains, especially in the scale forums.
