Give me a class 60 anytime over the yanky 66.
The 66 is weakkneed and vibrates so much it makes your eyeballs bounce.
Class 60 will waltz a full load of stone from Rylstone Quarry at Skipton as though it was going light engine.
Once it has RR the Train at Skipton, the 60 will be upto full speed of 60mph and you would not think you had 2600 tons behind you.
As the cab is seperated from the engine, the cab is moderatly quiet and nice and warm. The only problem is the electric motor on the cab heater tends to be a little loud on full power.
As for comfort, the seats are fine and will recline, and good for
12 hr ballast job.
