I think it's a great idea. It would be great to have my rule books, publications, manuals, route packs, notices, rosters, the lot, on a tablet. It would save such a lot of space and weight in my bag. I don't think there's a substitute for a paper diagram for the actual work as I like to mark up route indicators, train lengths, cross off stops etc. I personally think there are a hundred distractions and it's part of the driver's job to minimise and manage them. Having it switched on and silent is fine, as long as you don't use it on the move. But if I'm suddenly asked to do an unfamiliar shunt or need to fix a fault and can't remember where an MCB is, it's then on and ready to check the relevant document. And it would be very handy to actually receive real time information so that we're not sitting there like lemons making PA announcements saying we don't know why everything is delayed while the punters are seeing the reason on their Twitter feed. Yes we have general broadcast facilities but I reckon I can count on one hand the number of times I've seen it used in 5 years - and knowing the signaller will be trying to deal with all the stuck trains you don't want to be one of a dozen drivers all calling him at once. The only stipulation is that if drivers are expected to use technology then there must be training and tech support provided for new and existing drivers - and this is where it's likely to fall down as retraining equals jobs uncovered. But not insurmountable, once everyone's trained then job done.
