I have come from overground where we mostly had HW, Clamp Locks and HPSS. What do you have?

Most LU point machines are either Four Foot or Chairlock. There are a number of Clamplocks, and M63s are becoming far more commonplace.
There are no HPSSs and only a handful of HW (IIRC 7 ends) at Waterloo.

Ok thanks for that, so can you tell me anything about the points that you mentioned. Or could you point me in the direction of some pictures or even better an animated description?

Then there were also going to be Surelocks just after I retired, does the Jubilee have them yet? |

One set at Wembley, one at Edgware and a couple at Stanmore I believe - all in the 6' mounted variety.

The HPSS are generally regarded as being an over-engineered piece of equipment by installers and maintainers alike. I dont think you will ever see them in huge amounts on LUL.
They do work underwater so..... thats always handy i suppose..... (tumbleweed moment)

In all honesty, IP67 protection is more than overkill.
Unless you were using the HPSS is some form of wierdly designed saltwater swingbridge, I can't think of a situation that would *normally* require IP67 protected switch motors.
