From 1st January 2013 the NRN system south of a line from the Severn to The Wash was switched off - 'mainline' engineers trains after that date will only be fitted with GSM-R when working south of that line, however, they will still retain the NRN (analogue) system for them they work services which start / finish north of that line.

Dear Mr Bateman

 

TfL Ref: FOI-1863-1213

 

Thank you for your email received by Transport for London (TfL) on 4
February 2013 asking for information about Signal Post Telephones.

 

Your request has been considered in accordance with the requirements of
the Freedom of Information Act and TfL’s information access policy. I can
confirm TfL holds some of the information you require. You asked for:

 

Please could you confirm whether Signal Post Telephones are in use on the
main lines between Amersham and Harrow on the Hill, for the use of
national rail train drivers, (including engineering trains which are not
fitted with GSM-R), in relation to communication with the signaller.

 

London Underground provides Signal Post Telephones (SPT) on the
Metropolitan Line between Harrow-on-the-Hill and Amersham to enable other
Train Operators, that are permitted to operate on this part of the
railway, to communicate with the Signaller.

 

The Train Operating Company which currently uses the SPT’s is Chiltern
Railways. The only other use of the route is by a Network Rail, Rail Head
Treatment Train (to clean the track of leaves/mulch and use the Met Line
as a path to clean Network Rail track on the Met/NR boundary). The train
is operated by DBSchenker Rail who use Connect Radios and therefore do not
require the use of SPT’s

 

If this is not the information you are looking for, or if you are unable
to access it for some reason, please do not hesitate to contact me.

 

Please see the attached information sheet for details of your right to
appeal as well as information on copyright and what to do if you would
like to re-use any of the information we have disclosed.

 

Yours sincerely

Felicity, this request concerns a line operated by London Underground Limited. LUL do not have NRN and nor will they be installing GSM-R; this only applies to Network Rail lines.
