The morning service I catch into Kings Cross is mostly a 12-car class 365.
I have noticed that some units really struggle to accelerate smoothly/rapidly from stations.
It feels like the driver is attempting to increase the power having got the unit moving, but then the traction appears to suddenly shut-off, re-apply, and then the same thing keeps happening. It then feels like the driver is reducing the power so as to accelerate more gradually, and then only once a certain speed is reached can full power be re-applied.
Were the conditions wet, I'd assume this was wheel-slip, but this seems to happen regardless of the weather conditions, and it only seems to happen on certain units, and more noticeably when pulling away from certain stations (Arlesey seems to be the worst).
Can anybody shed any l light on what is happening? Is it unit-specific? Is it because the units are in need of an overhaul? Is it something to do with the track?
