Getting authorised access to electronic versions of NR standards is largely thwarted by an almost paranoid level of guarding (even to the point when I was working for one of their principal contractors where there was actually no legal way that we could get the standard to the troops on the ground given the rules put around printing or distributing electronic copies). However, depending on what you are looking to use it for the following may be of help.

The principle of SMTH has not fundamentally changed since its original inception. The early versions of the documents came under Railtrack Safety and Standards Directorate which was split off into RSSB. RSSB have a far more open policy about its documentation. Copies of their current and superseded standards are freely available via their website.

Under this regime, SMTH as a whole (under the document number GK/RH0740) was made up of three principal parts:

GK/RT0231 sets out the basis of the testing process and contains information on the defined tests.
GK/RC0729 contains the various equipment specific test plans.
GK/RC0731 carries the investigation plans for Wrong Side Failure testing.

Given its age the content here will be out of date in several ways:
1. The equipment plans will not have much of the newly introduced types of equipment.
2. The job titles and other terminology reflect several iterations of organisation from the past.
3. Scope - the last version of SMTH reflected the fact that SMTH was quite often abused to carry out complex jobs where the individual elements were all within scope of SMTH, but there were so many elements and SMTH did not have the "management of testing elements". For this reason, the G110 module was added to the Signal Works Testing Handbook to cover the management of such jobs and SMTH scope was clearly defined to exclude "extensive and simultaneous" works. G110 is the subject of a whole other discussion should anyone be interested, but I'm not going into that now!

Anyway, if you are looking for SMTH to understand how an infrastructure manager deals with the testing required for equipment changed associated with maintenance and faulting activities, the versions of the documents linked above will be a very good (and largely still valid guide).

If you have any specific queries about the content, please feel free to ask.

Many thanks Peter for your response, I just like to read and learn all the time so this is excellent for me, many thanks.
