Xbox 72 Stock Accelerates Differently In Scenario Mode To Timetable Mode

In the scenario A ROUND HAUL the 72 stock accelerates differently to timetable mode
Im not sure if this problem occurs in any of the other scenarios but it definitely does in this one
If you put the handle straight to parelell the train fails to accelerate at an appropriate speed
Please DTG can you look into this problem it ain't the worst game bug I've came accross before but it can be a pain when your trying to complete the scenarios.

 

Just wondering- in the Scenario is the Rate switch (up and to your left) set to Rate 1? That setting limits acceleration (usually used for wet rails, or slow depot movement)
