Underway - Duplicate Player Consist suddenly appears coupled to existing consist

[TacomaSailor]

OR V08

I created a very simple test activity that starts at southern most track in Surfliner 2 - a single path north to Oceanside - NO AI traffic

consist with two GP38s (#484 & #518) and 10 wagons

Running north thru San Diego Yard on yard9 at 15 mph

As player locomotive passes out of the yard, (give or take a few hundred yards), there is a flash on the screen and suddenly there is a duplicate player consist in front of the original player consist

Sometimes I am looking (forward from player cab) at the rear of the last wagon in the consist and the PAIR OF consists continue north. Other times I am at the front of the duplicate consist and the PAIR of consists is heading the opposite direction (forward for the new duplicate consist) that the original player consist was heading.

If I allow the consist to continue along at 15 mph - eventually OR fails with a variety of errors

Any ideas?

All I was trying to determine was why in Surfliner 2 I can run many different locomotives in Explore mode, but get an out of memory error when running an activity. Never seem to have the problem when using default MS equipment or many other types of equipment. So I created the simplest possible activity - one consist, one service, one path, no traffic - and strange things happen!

Tried the activity in MSTS with no problem

Went back to AE and deleted the player service - recreated - saved/computed - ran in OR and it now works OK

BUT - if I change the player locomotive to one of a number of other locomotives I get the out of memory error
