I heard an automated announcement at Hammersmith tube today, that I don't remember hearing before, advising that smoking was not permitted on the London Underground or at "London Regional Transport bus stations" - so TfL are just as guilty as the train companies.

The classic problem with software managers is that they often fail to understand the difference between something being conceptually simple and easy to implement. This then means they fail to realise how long something should take to implement properly.

I think it has been a DfT requirement recently.

In London when we were about 11 we had someone from TfL come in and spend half a day discussing safety on public transport in general, including hazards on/around tubes and trains. A few things I remember were the hazards of the inter-carriage doors on the Tube, danger of vandalising safety...

It could well be an electrical effect. You can often feel something which sounds similar to the description here when touching the case of a device (Apple products in particular) with an unearthed charger and Y capacitors to mains. The current in that case is usually in the 10s of uA, and I...

It was the same when I was in Vienna. The penalty for evasion was around €150, IIRC; but a year's travel was only about €400 or a month for €49. So you didn't have to be caught many times in a year for fare evasion not to be worthwhile.

I think this sort of thing is common in Europe - when I was in Vienna both the U-Bahn and the buses had announcements for bus and tram connections (although nowhere there had anywhere near as many buses at one stop as London!)

The issue here is not actually impedance, as this is the fault condition of a transformer being connected to DC (impedance is only meaningful with AC), but straightforward resistance. An ideal transformer has a DC resistance of 0 ohms (ie a short circuit). Of course as discussed a real...

Not a railway electrics expert, but I'd assume that neutral of the socket is connected to the train's earth. So touching live and any exposed metal (e.g. the socket casing) would be dangerous.

Not sure what the actual rules are, I had no problem using a photo I printed at home for a photo card though.

Most famous of course being "Inspector Sands" on LUL and in some rail stations

Interesting that they say "London Waterloo and Bournemouth" (as opposed to Poole or Weymouth)

Particularly as 25kV AC going into 1500V DC system; and 1500V DC going into a transformer are both likely to be pretty catastrophic...

From memory, I mistakenly tried to add a 16-25 railcard to an anytime ticket before 10am on a SWR TVM last year and I was given the choice of increasing to the minimum fare or removing the discount (I presume the former is for other railcards which have extra benefits).

Interestingly, in other parts of the SWR network using 5 carnet tickets is cheaper than a 7-day season. e.g Brockenhurst to Bournemouth Carnet £76 (£38 for 5 days) 7-day season £39.30 Definitely the other way round for longer journeys
