Hello Two questions: 1) Sort of Met related. Driving past the railway embankment at Amersham this afternoon I saw a Chiltern Railways train that had stopped on the line in service. The driver had got out of the train and was making a phone call from the line side phone. Does anyone know what happened and is it common for the driver to use the line side phone? I thought that trains had in cab radios. 2) Coming back from London to Chalfont today on the Met. When we arrived at Finchley Road an announcement was made over the tannoy by the driver informing us that we would be delayed for several minutes due to track problems. After a few minutes all was fine and we were on our way. Does anyone know what was meant by track problems? Thanks  |

For number 1..Perhaps his radio was broken and he was telling the control box.

On the mainline, drivers regularly leave the cab to talk to the signaller.
Also a very good strange event, yesterday evening was a Semi - Fast train to Chesham, formed of 5090 and 5068

Chiltern rolling stock do not have connect equipment and till summer when i worked in cabins serving the chiltern routes we used the SPTs or shouting out of the window method. Our line control room I think still has the radio equipment that is used on the national rail side.

What with Signal Post Telephones now being taken out of use, unless the Cab Secure Radio is used in the cabins now, messages about passing signals at danger will go via the service controller?

What with Signal Post Telephones now being taken out of use, unless the Cab Secure Radio is used in the cabins now, messages about passing signals at danger will go via the service controller? The Class 165/168s are fitted with the national rail Cab Secure Radio System (CSR) which is a secure radio system which is required for DO operation. The facility exists whereby the Chiltern Line drivers can communicate with the Met Line Controller when operating over LU managed infrastructure but not directly with the signaller at the three controlling signal boxes. This means that whenever they require to apply a requirement in the LUL Rule Book necessitating communication with a signaller, they must use the SPT. However, for the communication of certain messages, no doubt provision exists for certain messages to be passed via the Line Controller if for example an SPT was defective. CSR and NRN (National Radio Network) which are the two legacy train radio systems available on the national rail network are in the process of being replaced by GSM-R (Global System for Mobile Communications - Railway). More information can be found at: en.wikipedia.org/wiki/GSM-Rand www.gsmronline.comI don't know whether it is the intention to provide the signallers in the 3 Met signal boxes fixed GSM-R terminals to enable them to communicate directly with drivers or vice versa or just again to provide a facility for the Met Line Controller in the same way fixed terminals are being provided for Network Rail Route Operations Control Offices. The East London Line (London Overground) from Highbury and Islington to New Cross / New Cross Gate was provided with GSM-R from the outset. Drivers much switch over between GSM-R and CSR at New Cross Gate although in the Up Direction, they can pre-register their GSM-R train radio at West Croydon and Crystal Palace. |
