National Railway Network Frequencies

Post by Jonjo Robb » 04 Apr 2010, 17:18

Hello,

I have come across a page about the National Railway Network Frequencies here: http://www.radioreference.com/apps/db/?sid=2800

There are 28 nationwide frequencies, and I was wondering if anyone knew if they are still in use? Just wondering whether or not it would be worth me programming these frequencies into a scan bank the next time I use a train.

If it helps, I am situated near Keighley, Leeds. The local steam railway use PMR446 Channel 8 for shunting operations, but that is as much as I know in terms of listening to trains, as well as the mainline stations on 453.550.

Thanks,
Jonjo

Dont know what is on them Freq's, unless it is the back to back radio's we use at weekends on the renewals job's....but i thought they were on 172Mhz.
You would be better off listerning to the In Cab Radio's as they communicate with the associated signal box's up in the 454Mhz segment and then you can find out if a train has broke down...if someone has jumpped in front of it or if there are any signalling faileures, that will hold up your journey.
RADIOS: Kenwood TS-140S, President Lincoln, Kenwood TMD-700e.
AERIAL'S:Antron 99, Spitfire 3Ele, Diamond X510, Spinger(Red).

York zone control channel is on 205.83750 and Doncaster zone on 206.10000. The control channels are time shared with several controllers in each zone.

Cab Secure Radio is only used by about 4 out of the 26 train operating companies (passenger only) It's used in in Glasgow (ScotRail Glasgow Suburban / Ayrline electric trains, the diesels use NRN) Southwest Trains, MerseyRail and one other which I can't remember). It is only used in the Glasgow / Livepool / London area's, or trains originating or terminating in those area's. There is tests being done for GSM coverage which means it will soon go off analogue, both CSR and NRN (National Rail Network)

Hi,

Thanks for all your replies - I will certainly add those frequencies to a scan and see what I can get. I guess I will only hear the Train side of the communication, as I don't think I am near any of the Transmitters.

Thanks,
Jonjo

Hi M6AXL,

What frequency have you heard from there? - I am in the Worth Valley so I am not completely Line Of Site with Keighley Gate - I have always wondered what is transmitted from there!

Thanks for your help,
Jonjo

Jonjo, you can hear absolutly everything from up there. I use that spot for contesting and have worked Europe on 10w UHF no problems. You can hear alot up there, just got to filter out the rubbish. The transmitter there is pretty redundant only bradford council use it now for cctv and microwave link. If you ever want to go up there for a good listen let me know and I'll meet you there, its only 2mins from my gaf

Well, I walked up to highest place near me - the Trig Point just north of Ovenden Moor Wind Farm. It is at 451 meters/1479 feet above sea level. I could see for miles - and hear the NATS Preston Transmitter full strength!

Unfortunately, All I got on the most of the NRN frequencies was interference, white noise. On some of the frequencies there was what sounded to be data bursts, about two seconds long and one after the other. It did not sound like the MPT-1327 control channel of the local Bus Company.

There is a transmitter up there by the turbines - whether I was receiving interference from that I don't know. If that transmitter is connected to the turbines, I also don't know. Its not a phone or Tetra Mast. Did not look like a TV one either.

Thanks,
Jonjo

NRN still hanging on in the North of Britain but GSM-R will fully take over soon.

205.675 is normally the shunting/yard control channel.
