Like all freight engines Lead or dead is the correct setting but when I'm running it on LIRR trail24 or 26 is what it's supposed to be on that's not right
There is a thing with the MU valve on this loco that when you first hover over the switch it looks like it’s set to Trail but it actually works like it’s set to Lead. If you operate the switch at all you do then need to set it back to Lead to drive it. I haven’t used it on another route but that is how it has always been on Peninsular Corridor.
