Hello PJW,

Hope you are fine. Its the time of year when those taking the Module 2 exams need the revision and practice hence the visit to the forum.

Appended please find the summary comparing ABCL, AOCL, AHBC and MCB which I had submitted to you in late May this year for your comments. Thank you for your valued comments and for the benefit of others taking the module 2 exams I would like to post them here complete with your comments on my summary.

Level crossings are included in almost every other year if not every year.

From the ORR Guide that I reviewed, AOCL is not favoured by Network Rail for new crossings and so for the exams if we are signalling to UK mainline practice, AOCL need not be considered as an option. Please correct me if I am wrong to come to this conclusion.

My one question on your comments on the ABCL is that how will the SIP be determined without the 27 sec rule which you deleted?

Hope this summary is useful to all.

Cheers

Alex
