Super, thanks! 2 Together for £15 - and should get this back in a single Swindon to Heath High Level journey next year :)

I would agree with the comments around the process of either scanning/tapping at TVM, or entering serial number plus check code of some sort to cross check at purchase time.

I'm wasn't arguing that : I'm pointing out that liquefaction of air (as per post 5...) is not the way that CO2 is obtained for this or any purpose... This is drifting OT... The technology is interesting - will be interested how it pans out.

Yes, but the amount of CO2 obtained this way is small (and not enough for all the uses). Air is 78% N2, but only 0.04% CO2...

It isn't - it's a very inefficient way of obtaining CO2 (hampered not only by the low percentage, but also by the fact that you must compress CO2 to get it into a liquid state as it sublimes/condenses directly from solid to gas and vice-versa at atmospheric pressure). It's a waste product from...

Suspicious, but not impossible, even without beer! I managed to regularly sleep on a 13 minute journey during my commute (but didn't oversleep once - familiarity with the line I guess..). If you have a lack of sleep prior, you would be surprised at the speed and situations in which you can fall...

And by 1971, it had been closed to passengers for 8 years!

Fair point, though some difference between routing through necessity/convenience of paths/not running round and routing a convoluted route just to get a bigger wedge of the charges! Going the long way in the old days via the S&D I presume doesn't solve any gauging issues...

Very interesting stuff - while the retention of business and profit makes much sense, the routings are utterly bonkers when viewed from a present time!

Similarly for the GWR and Southern: there is London - Reading. But this is an interesting one given many years prior to grouping, the GWR, SER and LSWR all did the same journey from different London Termini, until there came an agreement to fix fares and share fares in 1858 (ref: Branch Lines...

Fairly sure I have mentioned this before, but Selhurst on the down fast used to be a big step up to the train. Not sure if that is still a booked call? (Used to be used a lot on Sundays for E Grinsteads)

Many thanks :-)

Thanks for that - I'd assume there is some procedure on the side of the signaller (reminders? Does it ever occur where signals would auto-revert to red with a train in the circuit ahead of the signal, etc? - sorry, I ask as an interested outsider!) Also, anyone have images of this type of...

Split this out of https://www.railforums.co.uk/threads/caledonian-sleeper.176365/post-5272955 : "Standing Ahead Controls" I presume is the ability for a train to shunt onto/leave a platform with the leading end past the platform signal? I'm fairly sure I've seen this at Swanage when we went...

Sound propagation, especially at night, can be remarkably different to the day - the presence of a temperature inversion layer can result in sound waves being refracted back towards the earth. This can result in sounds being audible for very large distances. Valleys can also help "channel" the...

Fails the fares check on the routing point for Merstham? The fares check (likely) passes as the destination goes further away (so using Redhill as the routing point passes for Merstham -> Finsbury Park for example).

I've only seen it once - many years ago, but a little odd given it was Whyteleafe, London bound at the end of the morning peak, where the train sailed through - I don't think there was ever any planned skip stopping at that time. Not so bad given the short walk to Upper Warlingham...

Not seen this referenced on here, but looks like there was some substantial damage to the Up Line between Wallers Ash Loop and Micheldever caused by what appears to be a short from the 3rd rail. Looks like single line working has been in place today until the rail can be replaced tonight...

I would already expect a reworded/recoded easement to arrive at some point...

Looks like the easement is gone in today's version of the easements pdf file (21/06/2021)....
