FNA flasks

[firetrap1]

I'm creating a railworks scenario for WCML North and am interested to find out if anyone knows the max speed limit of FNA flasks when combined in a formation of 2x class 37's (double headed) and 3x FNA flask wagons.

I know from just half an hour of research that the max speed over bridges and viaducts for any loaded FNA wagon is 50mph. But in the interests of creating a realistic and achievable timetable i was wondering what the main line speeds would be as im assuming that they would not be greater than around 65 ????

cheers in advance.

I know the overall wagon speed to be 60mph - but that may only be when empty.

I have a feeling it may be either 50 or 45 when loaded (though of course different regions have their own rule books for these things).

They shouldn't be 65mph, but IIRC it is 60mph though it *might* be 50...

Loaded or unloaded they run as a class 6 headcode (60mph freight but also accounts for 50mph) if it was 65mph it would run under a class 7 headcode.

Almost, 65, 70 and 75mph are class 4.

Yes your right class 4 is what I meant, class 7 is 45...went the wrong way through the numbers
