i recon i should be able to compare them quite easily, after driving 66s for so long i have a good idea of what sorts of speeds i pass certain places with certain trains, similarly with throttle positions, getting one on the logs will be interesting to see how it goes up gresford bank with a loaded train, similarly shap with an empty one
its not just performance that i will be comparing but driver comfort, sound, vibration etc
i'm training on them the week after next so hopefully i can get on one pretty soon with a train
