Network Rail make all of there standards available via a subscription service offered by IHS.com which effectively means you have to pay. They impose the duty on the subscriber not to copy or distribute standards which means that I cannot pass one on to you.
The recent version that you talk about is probably NR/L3/SIG/11303, however, there is not that much new in it compared with the old RT/E/C/11210. The new version is merely a reformatting which makes the standard into an index with each of the individual sections as separate stand alone appendices. The vast majority of the appendices are unaltered from the earlier issue. This has been done so that they can update the appendices gradually without the need for re-issuing the entire standard each time. There are only a few updates to the appendices that existed and there are a couple of new ones for equipment which was not around when the original standard came out.
If you have a copy of the old one, you have most of the information in the new one, but this does not mean that you have up to date information - it is still horribly out of date even though re-published!
