Quote:I would like to have your reply for below queries as soon as possible.
I am expecting your answer for question 7 and 10 in 2008 layout thread (Module 2).
Please explain OTW-NS, NSTR also.
I am afraid that pressures of the day job and social committments currently prevent me dedicating as much time as I might otherwise have been able to. I appreciate that the exam is imminent and there are quite a few people with their last minute queries so I simply can't address all I regret.
One Train Working- No Staff and No Signaller Key Token are both mentioned in the Module 2 Study pack Glossary and the relevant UK standards are cross-referenced and these can be downloaded from the internet as described in the References section.
Also if you look in the "Powerpoint" subdirectory within the module 2 Study Pack you will find that "Single Lines" ought to provide useful information
You may also find other information on the internet such as http://en.wikipedia.org/wiki/Token_(railway_signalling) is useful to you
