I gather that there is a portable GSMR, I've never actually seen one, but I've heard it discussed at work if a radio fails, its at outstations.
how much would it cost to fit GSM-R to a kettle? I'm guessing someone paid for NRN and CSR to be fitted before that?
Heathrow Expeess and Connect trains are not fitted with GSM-R, they still rely on CSR. The company refuses to pay the installation costs so is GSM-R essential?
A few years ago, before ATW started to fit GSM-R to lines away from the Cambrian, there was engineering work on the SWML which necessitated the use of GSM-R. Drivers were issued with handhelds (SagemCom, like the above link - but yellow!) leaving Newport and Cardiff, and handed them back in at the other side.
These were IVRS handsets, not true GSM-R, it could only be used for the railway emergency group call function and then only the driver could initiate it.
The portable GSM-R kits are a huge suitcase affair, as said "portable" is a bit of a red herring.
TheEdge said:Well, they are portable in the most basic sense of they are not attached to a train and can be moved. The fact they need two or more people to move them safely is another matter...
Yes, one day CSR will be turned off, and infact everywhere below a certain point is already turned off, where that is I cannot remember!
What is the handset doing that can't be done in the size of a normal GSM phone? Has it got a black box tape recorder of some kind?

I think it was just the National Radio Network (NRN) that was switched off everywhere in the south, i.e. 'below a line'. (The line being from Severn to the Wash.)
I doubt the company has a choice. When NR want to switch off CSR then there'll only be GSM-R. My guess is that it's likely that they haven't (needed) to get round to it yet.Heathrow Expeess and Connect trains are not fitted with GSM-R, they still rely on CSR.

Another point to make is that GSM-R provides other functions other than communication. For example, it is tied into driver vigilance/DSD systems to send an emergency message to the controlling signaller in the event of something bad happening to the driver. Admittedly this may not apply too much to heritage charters, but it does illustrate the point that the GSM-R is more than just a phone.
