I have had one "forgot to stop", two "near misses", and seen one unintentional "miss". The first was in the steam age - travelling from Bolton to Manchester, the driver forgot to stop at the (now long-closed) Pendleton, not even reducing speed.
Next was an evening London to Liverpool service, one of the few that then called at Hartford. Driver almost forgot about the stop, then slammed on the brakes -- he just managed to stop but with 4 or 5 coaches beyond the platform. (Liverpool drivers often seemed in a hurry to get home on those late evening trains; loco was a class 90)
Then came a railtour, with a Class 85 returning from Scotland; driver had obviously forgotten about set-down stop at Earlestown, so steward pulled the cord, and already travelling at low speed, we managed to stop with rear of train in the platform.
Lastly, the driver tried to stop, but the pair of Class 150s slid slowly through Chapel en le Frith at about 5 mph due to poor rail conditions. He eventually stopped just beyond the platform, and after a little delay, he got permission to reverse into the station.
