My source for the tc lengths is an Irse text book. I am referring to the AC vane type for dc immunity.
My confusion is not with the type of Tc (af tc ect). I'm Aware which use irj.
My confusion originated with the belief that TC through point work should be double rail, this is obviously incorrect. I then began to think that the single rail tc is preferred for long plain line, due to the fact one rail could be irj free for traction return, maintenance, passengers, imp bond saving. This must also be incorrect.
I will check the NWR standards for lengths.
Thanks.
