  • why was it doing that?

  • @Hornbylad200 - Rescuing a failed Eurostar. The detonators were protecting the unit by acting as a warning to oncoming traffic as per safety regulations.

  • A Eurostar?

    On the ECML?

  • @THAMESLINK319 - Yes, but quite a while ago now. They GNER hired in units to run Leeds services.

  • @bbgunsrule324 They act as warning signals: if there is a problem up the line, these can be placed: if personnel is on the tracks near the (for example) defective train, and they hear these things go off quickly (not as slow as in this video), they know they have to get to safety fast. We do have them in Holland, but as far as I know not in regular use anymore (only when drivers retire some of them will be placed on the tracks) Shorting the opposite track is our safety-measure.

  • i dont understand why the little bombs were exploding

  • These used to be used in the US, we called them torpedoes, but they've been mostly supplanted by fusees (flares).

  • Are the detonatoes kept in every train cab? Does/can the driver sets them on the track?

  • what are detonators

    

  • They are placed 300 metres from the train, 22 yards (20 metres) apart. The driver must wait by the detonators ready to pilot the rescue loco to the failure. They are also used at the ends of possessions. AWS and TPWS have eliminated the need for fog detonators, along with colour light signals.

  • Dets are placed to stop a train in the UK. In this case the class 67 driver has already picked up the failed trains driver and now approaches the failed train. They are required by the rules to leave the dets in place and run over them to enforce the caution.

    The third det isn't a full 20 metres but the driver who placed them doesn't carry a tape measure ;)

  • My understanding is that track detonators are to notify a crew working on a line that a train has passed a red signal and is bearing down, quicker the bangs, faster the train is approaching and of course if you are the driver it tells you that you are on track that should be closed and to stop immediately.

  • Very interesting. Thumbs up! :)

  • I LOVE DETONATORS!!!
