I do not wish to seem brusque but I am wondering if not everybody reads my posts in considerable detail. I would like to make this quite clear; I am not disputing the levels of concentration required; merely the type of concentration and the duration of the spells of concentration.
Referring to the question posed by the original poster, namely the use of the Group Bourdon test for conductor assessment, this test of which I have had direct experience requires the applicant to concentrate on one item and does not take account of multi-tasking. This is probably why certain companies prefer to use the SCAAT test.
Referring to the example described by red2005 of platform despatch whilst monitoring signals, platform activity and queries from passengers, this example vindicates my belief perfectly well of the need for a guard to switch attention between different sources of information or stimuli. Would anyone lime to comment about the average duration of a train despatch?
To be quite honest, red2005, I found your earlier comments where you pleaded for me to refrain from applying as a guard, to be somewhat derogatory. There is no doubt in my mind that with the appropriate training, that I would be able to perform the duties in a safe and competent manner. I am sure that I have quite a realistic perception of my ability to concentrate to the levels required.
Again, red2005, referring to your example of protecting the train. Exactly how often does a conductor need to walk besides the track with detonators? For example, when the driver has been unable to contact the signaller or the signaller cannot arrange protection. Also, when would the conductor protect the train instead of or as well as the driver?
Monty, thank you for your input. The prospect of guarding a train of twelve carriages does seem somewhat daunting. I have actually been to some of those stations, but as I do not have a book of track diagrams for the Southern region, I would not be aware of the need for selective door opening at the smaller stations.
