Looks like this scenario has gone fubar as I tried it twice and the game is not acknowledging that the fuel tank has been filled! The loco tank is almost full when we get to the fuel point anyway so the tap turns off as soon as you turn it on so whatever DTG have done to the Christmas Closures scenario might have knackered this one which means the Peak Performance achievement is now broken as you can't get past the fill fuel tank instruction!
There will probably be the usual workaround of completing this scenario on TSW2 and then importing that profile and completing the scenarios on that profile but having to mess around like that really shouldn't be needed!
I've just tried to recreate but come up against a different problem. Following the instructions as given in the task list I set the speed set to on at the data screen, then set the speed set to on on the control panel, then it asks me to put the reverser in reverse, but gives the location as 10 yards away from the drivers seat. Looking at the location it's somewhere UNDER the loco... I took a screen grabbed vid of it if anyone cares to look
The Class 66 in the video is from South Eastern High Speed Extended, not Great Western Express. This could be part of this issue in the original post, as well as the issue with the objective marker.
Aggregate Industries works only with the original GWE Class 66, here is the solution for you. Other Class 66s cannot be refueled or have unreachable objective markers.
Thanks, I'll give that a go but it really shouldn't be required to have all these problems cropping up
