I am not aware of any buffer-stop collisions at Bradford Interchange.
However there was the unfortunate accident in 1964 when a dmu ran away down the hill and collided head on with a parcels train in one of the terminal platforms of Bradford Exchange, sadly killing the driver and injuring 13 passengers, one of whom died of their injuries the day after.
I was in the area at the time, and the memory still haunts me.
The history of Diesel Multiple Units (DMUs / railcars) in Britain.

To continue with the historical examples:-
In the 1960s, the Halifax portion of the morning train to London Kings Cross used to go to Huddersfield, where it reversed, then go on to Wakefield Kirkgate, where it reversed again, to be pulled up the chord to Wakefield Westgate to siding at the north end of the station, where it awaited the arrival of the main train from Leeds Central, and the portion was then propelled on to the rear.
3 coaches, 3 reversals in about 20 miles, with the fireman of the same tank engine un/coupling and running round.
Such was the importance given to through coaches in those days!
