2004 Point CT
#4
Before I comment, I should stress that I am not a wizz on CTs - it was my worst mark when I did the exam, but given that I did pass module 3, I can't be too far off the mark.

I've had a look at your table for 203 points and as far as I can see, it is very good. You appear to have adopted the practice that shunt moves will not have overlaps which is fine, but you may be advised to state this.

As far as I can see, the only route that you omitted in the "Set by" was 142B(W) calling them R to N - there is only one ROL shown, so there is not a swinging O/L issue there, but you had not mentioned the route atall. The warner should probably be shown in the TOL box as well (you got 142B(M) in there).

The condition for releasing the locking on R>N for the line (142B(M) or 250R...etc) has all the right TCs to be clear, but I wonder whether you should have DB or DC in the occ col - look at the length of the platform against the length of the train. Something could well come in to the up loop from 142 and sit at the right hand end of the platform never touching DB track.

Where you have showed the swinging overlap controls, you have done so, as far as I can see, correctly for R>N but on the N>R sheet you have shown the essence of it, but not used the swinging O/L columns and I wondered why. Perhaps is it that there are no additional TC required to be clear, so you did not need to use that col!

All in all, a very good effort. I'll try to look at 211 for you later.
