Comment 3 for bug 1948545

I have been experiencing the same thing using using SNCF rolling stock. On resuming an activity the wheelslip indicator continues to sound and despite getting up to and holding a decent speed the throttle rolls back to 0 slowly without continually pushing it up. The wheelsip cannot be overcome. This only occurs with some models and the same model used on any route produces the same behaviour.

Frequently occurs to the Bombardier AGC series linked to below.

Note this has started after upgrading to version 1.4. Reluctant to go back to 1.3 as the graphics is sooo much better and runs smoothly.
