Under Powered? Class 66

[Andysim]

Im was looking at Railway Magazine and in there it says about GBRf getting some coal new HTA Coal Hoppers, They are almost identical to the ones used by EWS, anyways they are 100t each and they are to be run as a set of 20. I asume EWS runs 20 and Ive watched videos and seen the EWS ones in sets of 20.

I set up a 20 wagon EWS train and the Class 66 EWS from the D/L station and set up a route on the Yorkshire Plains Route (My Favourite route BTW) and going from the mines to the Powerstaion. 1700t

The Train took ages to get anykind of speed up I began to Wonder If it would ever get there. 10 Minutes later and still gaining speed (on the flat)

The Switch was set for the Powerstaion and the train Began to Brake.
It Went through the Coal Drop Off Point and was out on the Main Line again before it stopped 0-) lol

Ive since put in a 20 mile an hour Limit on the Left Powerstation Exit and began Double Heading, But I wonder if thats realistic?

Well it might be a bit out but you certainly would expect such a train to take a while to get up to speed and then to brake again, it is after all moving and halting a huge amount of weight.

*enters with maths cap on*
If you think 100t X 20 HTA's = 2000t's of coal ...
Thats a pretty heavy weight to pull
i would go on with algebraic equations involving spec's of the 66 and the cargo, but

A) i don't know the specs of the 66
B) i thought i might bore you to death

Thanks,

Yea the thing is the Class 66 on the Video was quite certainly no layabout. Not as slow pulling away as the one in Trainz.

Its on Rail-tv "British Diesel Directory General Motors Classes" Its called.

Looking at the enginefile it doesn't seem underpowered if the figures are to be trusted. Saying 429,5 kiloNewtons starting Tractive Effort in run-8 from standstill. That equals 96500 lbs and an adhesion of 36%, which is even better than an EMD SD40 - this providing the sim is calculating a-ok.

I've tried the class 66 a while ago and didn't find it particulary sluggish but I've also made some pulling tests on grades with very heavy trains with variable results. In my opinion Trainz is exaggerative with rolling-resistance in curves which becomes very obvious when hauling long trains.

One must not ask a computersim to be 100% authentic but Trainz does things with such grace, so one tends to become a bit spoiled and demanding...

Is this on AI mode?

If so; you need to open the Config.txt and find the lines that control DCC braking/accelerating. This is what the AI uses. IT'll be something like max_accel/max_decel. Change these figures to 9,000 for max_accel and 100,000 for max_decel.

The 66 should now have a bit more umph in AI mode!
