Thanks for the reply.  Here’s the thing...if I physically turn the train around on the track so the rear truck is first through the switch, the results are the same.  The second truck will not go through the switch. The first truck regardless if it is the rear or front slides through the following truck will not. I have tried this locomotive on multiple switches and this always happens.  No other locomotive has an issue with the switches so I have concluded it’s something with the locomotive.
