Hi Arnut

Some more feedback on these:

Route 416B(M)

overlap via 237N should require 234N
overlap via 237R should not require 234R (flexibility)
365B routes should be considered opposing
351BM also opposing

Route 416B©

Track circuit controls have been shown as for a main class

Route 365A(M)

overlap via 242R, 246R also requires 247R 248R

371D(S)

also requires 238N (flank)
locking applied by presetting route 365D also requires release by CD CE clear
signal control condition ED clear or ED occ is always true - solution is not to test ED in any state.

235 points

should also be called N by 371D & 373 C - flank

236 pooiints

do not need to be called R by 416C or 412C - do not provide flank


Overall some very good responses, difficult features well handled!

best wishes
