There is a good reason for that, air conditioning de-humidifies the air as well as cooling it. This means that slightly cooler, but much drier air will not only dramatically improve the rate of demisting, but will also reduce the amount of misting as the air in the car will be drier too, and therefore less water in it to condense on to the screen.

I expected a tense response!

I know about a computer trying to park cars in a car park. It was very depressed.

Is this the time travel joke?

The solution is very simple. OLE does not need the precise horizontal alignment that track does, so if you can line up the track good enough to avoid derailing, then OLE will have no problem at all. There will be no issue with having a single solid wire or conductor on the traverser. Wire the traverser with a single wire to the centerline, which extends say 10-15mm beyond the end of the traverser, with a slight upward ramp so the end of the wire is 2 or 3mm higher at the end than it is when above the traverser. You then have a similar overhead arrangement on either of the two roads with approx 15mm or so extension over the traverser, except the top road is offset 5mm or so past the center line, and the bottom road 5mm or so before the center line. This means that the traverser can move between the two roads with the OLE on the traverser moving between the two. The OLE in each position will have a horizontal gap of 5mm, so both wires will be over the pan as the pan exits the traverser, and the pan will transfer seamlessly from one wire to the other where the wires cross vertically.

Is this the five minute argument or the full half hour?

Not according to this!

Pretty sure the rails are the same height. The switch rail that the skid passes over is "floating" as it is not connected at either end and the skid can run over it without shorting. It only becomes connected when the point is thrown the other way and the switch rail contacts the stock rail, and then of course the skid runs over the other now disconnected switch rail instead. There is a risk that a wheel passing through the gap could cause a short, but if the b2b is OK it should clear it.

Not what I call a near miss. A near miss is considered to be a reportable event which does not lead to any damage or injury (let alone death) but had the circumstances been slightly different could have. It would not even have been considered a near miss if the truck had not hit the train at all, as it would still have caused damage to the infrastructure. -
What is this under the rear of Class 92 bogie?
Titan replied to wwrsimon's topic in UK Prototype Questions
It is most definitely an APC receiver, don't judge it's position using the rail as that is deceptive, note instead that it is in line with the suspension and damper on the left, which puts it in exactly the right position for an APC receiver. -

Titan replied to wwrsimon's topic in UK Prototype Questions
As it is mounted on the outside of the rail it will be the APC (Automatic Power Control) receiver. Works in the same way as an AWS receiver, and indeed looks just like one, but it detects the magnets fitted to sleeper ends before and after a neutral section to ensure that the loco circuit breaker is tripped and then reclosed so no current is being drawn when the train passes through. If it gets out of sync the driver can press the "pan up" button, even if the pan is already raised and it will reset the breaker. -

First thought was an AWS receiver, but it does not look like the standard one. It might be the ground speed sensor - it compares the wheel speed against ground speed for more accurate wheel slip control. -
Diggers like that are strong and heavy, and have been known to displace bridges significantly when they hit.

Thtandard. -
A similar vein to the old boating lake joke- "Come in number 9 your time is up!" "But we only have eight boats!" "Are you in trouble number 6?"

What would be the life expectancy for a card building?

Well I suppose one answer is "longer than RAAC"... I'll get my coat. -
Use of RAAC in UK railway buildings

There were not enough old ones. So you would rather people die than build the extra hospitals needed?
