William Huskisson MP▸ was the first person to be killed by a train while crossing the tracks, in 1830. Many more have died in the same way since then. Don't take a chance: stop, look, listen.

Also, if the GSM-R▸ radio is tied yup giving the driver non-urgent instructions, how would an emergency all-stop order get through at the same time? Slim chance, but it would eventually happen!

GSM-R▸ is more than just two-way communication though. If it's being used to talk to a signaller for non-emergency reasons an 'all stop' message can still be transmitted or received.
Still doesn't mean GSM-R should be used for train running amendments from TOC▸ control though.
If that were to be wanted then I suspect a separate discrete system would need to be fitted. Something similar to the ACARS system fitted to commercial airliners, which allows airline ground staff to communicate with pilots, separate from ATC▸ .

There would still be seconds delay I suspect if the driver was concentrating on listening to Control. Could be the difference....

Believe me, you don't miss a GSM-R▸ emergency broadcast no matter what you're doing in the cab!

Isn't ACARS a text system rather than voice? I'm not sure a driver would be able to use that effectively. Don't forget a commercial aircraft has a pilot flying and a pilot not flying at all times so there's greater ability to handle messages too. |

I had Allways thought that GSM-R▸ was in essence a mobile system that uses cells like a phone does so it should be able to receive a text message whilst making a call ? Please feel free to let me know if I am wrong  |

Please feel free to let me know if I am wrong I'm sure that the driver can be reached (as a last resort the Guard could enter the cab with a message. It is just that under normal circumstances I expect that he can't be distracted whilst driving. |

Presumably partly because it only springs into life when there is an emergency and not filled with general "chatter". |

I expect that would be easier than it would be for a guard to get into the cab of a class 91 on a moving IC225, which is also a High Speed Train (or is the MTU▸ engine so big you cannot walk past it even with ear defenders?). The IC125 I've driven on OpenBVE (a train simulator game) has a buzzer system though, so I assume the guard could buzz the driver to tell him/her to stop at the next station (in fact, come to think of it that must be how the driver knows if somebody wants to alight at a request stop, so to reinstate station calls the guard could simply buzz the code that means stop at the request stop). |

Don't DOO▸ it, keep the guard (but it probably wouldn't be a bad idea if the driver unlocked the doors on arrival at calling points).

Yes, driver-guard communication is fitted and in an emergency the guard could walk through the engine room - space around the engine isn't a problem (there's more room there than there is past the cooler group area), but it is rather loud so not ideal!

Having squeezed my generous frame through a Class 31 and 37 engine room dead and stationary, I would hate to think what a Class 43 would be like at full pelt. There's likely to be some pretty hot bits too...

I'm sure I remember reading somewhere there's an issue with walking through a Class 43 power car due to the fire suppression system installed.
