I'm not a railway worker, but I'd've thought it would take a pretty strong set of points to resist the weight of a train going through them "backwards". Certainly in the days of steam "catch points" were a standard feature on sidings - they were set to the dead-end spur to prevent unbraked wagons escaping onto the running line and all traffic entered "against" them - they were also used on gradients. They may indeed still exist on National Rail for all I know.

Funnily enough, that's actually something I do teach my trainees. I found that one out about 8 years ago when I used to do permanent nights. I don't teach anything else though, just that!  ;D ;D |

Indeed I also taught trainees that the points can be driven through, but only after being authorised by the Tower Operator. This is because, although the points are powered, they are not locked in position. In the event that you were to drive through them without telling the Tower, he would soon find out, as a bell rings in the Tower in the same way as if he sets one end of a crossover but not the other |

Points at SMD as soon as they sense a train is going to "trail" they power over to the correct position.

Points at SMD as soon as they sense a train is going to "trail" they power over to the correct position. Is that done with the pressure of the flange on the switch rail or with a delta track? |

As a Guard we were sent to work at The Tower at Upminster and I can confirm that yes you can push all of the trailing points provided it is at the depot speed of 10mph.
When I was training up there I was told that it was common practice to let trains run through the points of course that was in the early 80's, so things ain't changed much.

I'm sure I was told by my I/O (the loony S O'C for those that know him!!) when I first came over that the points could be trailed through.
Thinking about it, it may well have been our own trainopd78 who told me (seeing as he was accompanying us!)

I do inform trainees of this.
I *think* I found it out from the depot staff at some point, rather than having been told it whilst road training. But on the other hand, there is so much information passed during r/t it's not surprising if some gets forgotten!

It's news to me too !
On one previous ocassion I was cleared from the depot by the tower but the route wasn't correctly set. The train pushed through trailing points stopping on the blades as I applied the emergency brake. The tower man after demanding to know why i had stopped exclaimed some expletives and the DDM was sumonsed by him, after some examination I was told to proceed very slowly and stop if signalled to do so (or he'd move the train if I was unwilling). I was told there was a lot of paperwork was going to need doing for the occurance !
Certainly no mention that I could push through anyway by either of them ! ....and I'm still not convinced I'd be prepared to do it under instruction (is it written somewhere ?) !!!
