Random question regarding Cautioning trains.

[WillHaysNephew]

Hello, first post so please be gentle and apologies if this is the wrong place but…
In view of upcoming assessment and overhearing a conversation thereabouts, I have a random question regarding cautioning trains.
When can a train be cautioned on the move?
I know of rail adhesion issues, animals on the line and missing safety/emergency equipment (which I assume means missing tail lamp or missing TSR/ESR boards) but there must be more?….
Thanks.

Normally a train would be brought to a stand before being cautioned, in order that a clear understanding can be reached.

General stopped at a red with a text instruction via the GSMR to contact the signaller. You’d then be told what the reason for being cautioned was, the areas between which to run at caution (often bridge numbers or signal numbers), and what to do after passing the area. You’d repeat all that back to ensure a clear understanding, then proceed through the area and, depending on what you’d been instructed, either continue at line speed or contact the signaller again to report anything you’d seen.

Not sure what grade you are in , but the GSMR Handbook covers this and includes scripts for use . The GSMR Handbook section on broadcasts states .

Safety broadcast calls are used to reach a clear understanding by using non verbal acknowledgement.

After listening to the message in its entirety and after the call has been terminated the driver acknowledges their understanding of the message by pressing the ST button.

Safety broadcast calls can be used for the following scenarios.

• Poor rail conditions.
• Animals on the line (Not tunnels).
• Defective Emergency Indicators.
• Missing or obscured Temporary Speed Restriction (TSR) board.
• Unusual events (Not Track or Signalling).

Rulebook module TS1 also says the following

If the rules require you to stop a train to tell the driver to proceed at caution, you can instead use a GSM-R berth-triggered broadcast to tell the driver.

You can only do so if, in the particular situation concerned, an instruction allows you to.

In practice this means that it also has to be allowed in the special insutrictions for that signalling location .


As a signaller you won't be able to use one where you need to specifically speak to a driver to give them some instruction ,or reach a clear understanding . So say if you have some treaspassers you might want the driver to report back to give you updated location information or something . Or a defective signal or piece of equipment you need to reach a clear understanding with the driver if they are to recieve an incorrect sequence or you need them to confirm what aspect a signal is showing .

Ah! GSMR guide is the answer.
I’d kinda run out of places (and, being honest, enthusiasm at the time) to look. I was going down the route of when to caution as a basis opposed to how to.
Many thanks

Do you actually mean what circumstances would require a train to proceed ‘at caution’? Because there are many of those, including passing a signal at danger, making a wrong direction/unsignalled move, examining the line, proceeding on the authority of a position light signal and so on.

No, just when the caution can be done on the move.

Are you training as a signaller?

If so, perhaps worth asking your instructors/coursemates?

You’re thinking too much. Just take the examples given, answer the question and then get experience. Could literally be here a month answering what ifs.

Yeah I get that not every eventuality can be covered, but I was aware there was “the” list I needed to know.
Asking around was a case of “Ask three people, get four answers”
But I’m there now, thanks all.
