I don’t post often on forums and with regards to DOO I’m very much split on the issue. However, with regards to the incident last night at Worting (which I know no details about except what I have seen posted online), the Guard cannot have helped to move a train forward with such an obscured windscreen (assuming it was driven from the affected cab).
Rule book RSSB GE/RT8000 module TW5 section 2.3 states that if a windscreen becomes obscured or broken another Driver with the appropriate route knowledge must be provided for the train to continue. A Guard does not have the appropriate route knowledge and therefore is no use in this situation*.
A Guard (or any other competent person such as an OBS) can be used to accompany the Driver to ensure he or she is not too shaken up by the event and hit the emergency stop plunger should the competent person believe the Driver is not reacting appropriately to the situation ahead. They (Guard, OBS etc.) cannot provides route knowledge information in the event of broken window.
* please don’t get me wrong, an additional member of staff onboard can be very useful in controlling the public onboard to avoid an uncontrolled evacuation taking place and providing reassurance for the Driver but to say the Guard was useful in moving the train forward is potentially misleading. But if the Guard was so vital in this situation for the Driver, why are ECS and Freight movements allowed with just the Driver?
On a side note, I do find it strange that trains formed of 2 coaches quite often have a Guard, yet those formed of 12 coaches down South don’t. Surely it should be the other way around with 12 coach trains even having 3 members of staff onboard, and not just 2. With new ways of working, new technology etc. it’s a shame no one is having an intelligent conversation about what the future of the railway will look without a threat of a strike.
