I was also a passenger on the train that was "chillin'" (according to the display on its side) at Falkirk High with door trouble. Nearly everybody waiting on the platform piled into the following train, which departed rather full as a result, but I waited another three minutes and got a seat on...

That would be from Haymarket West Junction. Gorgie Junction is off the main Edinburgh-Glasgow line.

Yes, but then you'd have two OSSs that are either ineffective at protecting accelerating trains or could interfere with decelerating trains. More TPWS isn't a practicable solution. A measure that has been implemented in a few such cases is to install a permissible speed warning indicator and...

Selectively suppressed TPWS overspeed system (OSS) loops to control trains' speed on approach to diverging junctions are nothing new; they have existed for many years. The difficulty comes with attempting to use TPWS to prevent overspeeding at a junction by trains that accelerated from rest at...

When I went last year, the boat carried a maximum of 12 passengers (four of whom would have to stand or sit on the open deck).

Splitting distant signals are in use today at the following junctions: Hilton Jcn. (Up Main) Airport Jcn. (Down Main) Tilehurst East Jcn. (Up Main) Ruscombe (Up Relief) Acton West (Up Main) Stockley Bridge Jcn. (Up Relief) Muirhouse North Jcn. (Up Muirhouse) Tilehurst East Jcn. (Down Relief)...

That's a splitting distant signal. They were quite common at one time but then fell out of favour for a while. While there are a few modern examples around now, the one south of Perth is the last 'old' one that still survives. A splitting distant signal doesn't have the same function as a...

I gather the permissible speed through Platform 6 was reduced to avoid the need for additional TPWS loops to protect the conflict at Lee Loop Junction.

That's right.

Yep, I did that border crossing in 2008. I didn't see the contraband being stuffed into the roof of our train, but I remember watching while the border guards removed it all and piled it up on the platform.

I think you could draw a straight line over the railway around Wembley Yard that would cross over more than 50 lines, or more than 60 if you include the London Underground lines and depot at Stonebridge Park.

Yes; in 2014, with a flashing yellow aspect on approach.

Look at the geometry. The route towards Perth is straighter and therefore faster than the route to Dundee.

This signal is GB5144, and it did have a phone! Additional phones were provided on the double-track part of the East Kilbride line to compensate for the inability to use track circuit operating clips in an axle counter area that didn't yet have GSM-R.

The amendments came with instructions, albeit not detailed instructions. See example below:
