Please check my point control table of IRSE 2010 for point no. 137 & 148

Your post says about 137 and 148, but the attachment only has 148.
Not a bad attempt - you got most of the obvious stuff. A couple of things were there but in the wrong place and there are some things that you have missed.
No deadlocking tracs shown for R>N.
481B(S) requires them N not R
The overlap for 484 goes beyond the crossing between 148A and 148B, so by the same logic that you have included the routes from 484, you also need to include the route from 494 up to 484 which requires the overlap.
Not sure why you have included FK in the locking release after 482.
Probably the biggest area of error is where you have incorrectly looked at the routing for trains from 461, 463 and 465. For 461, you have taken the train diverge through the switch diamonds! (You may need to look up about switch diamonds) The route goes though 137R. Similarly, 463 and 465 cannot go via the diamonds, they go via the relevant bits of the ladder reverse. That said, if it were possible to go the way you sent it, the route locking release that you put would have been correct.
One point that I am not sure on (because I am a bit rusty and have not looked it up) is that I think there should probably be some time of operation locking on the points with routes up to 481. Perhaps someone using this in their day job can comment straight off.
Hope this helps.
