‘Rail Force One’: how Ukraine railways got Joe Biden safely to Kyiv
Alexander Kamyshin, head of the service, doesn’t get much sleep, but his team coordinated the president’s visit without a single leak

Alexander Kamyshin, the head of Ukraine’s railway company Ukrzaliznytsia, doesn’t get much sleep at the best of times. On Sunday night, as Joe Biden was being ferried into Ukraine in a 10-hour night journey from Poland – in a carriage now known as “Rail Force One”, he got almost none.

Along with others involved in the secret operation to bring the US president to his meeting with Volodymyr Zelenskiy, Kamyshin watched the progress of the train in a command centre.

A handsome bearded man sporting a hipster-ish braid of hair that falls over the shaved sides of his head, Kamyshin is deliberately vague about many of the details.

But in the past year, his dedicated team has brought in world leaders, VIPs and diplomatic missions on an almost daily basis as part of a programme called “Iron Diplomacy”.

Security is everything, he told the Guardian in an interview at Kyiv’s main railway station. “We have not had one leak. There have been no photographs from train attendants. We respect the confidence of the delegations.

“It’s not a challenge. It’s our job that we do every day. Imagine,” he says with smile, “the president of the United States coming to a war-torn country by train.

“The challenge is treat the delegations properly because, like Biden, they spend more time on the train than they do in Kyiv. He spent 20 hours on the train and four hours in Kyiv. Everyone knows Ukrainians are brave. We also want them to know that we are welcoming.” ...

It is hard to understand why it is valid Ashford-Waterloo East-Waterloo-Basingstoke-Warminster
also valid via Ashford-St Pancras-Paddington-Westbury-Warminster

but NOT valid via Ashford-St Pancras-Waterloo-Basingstoke-Warminster (at least, the Nat Rail JP thinks there isn't a valid ticket, which is the "de facto" indication of a lack of validity).

...and as for John Penrose's wish for lots of different rail firms competing to beat each others' prices, I despair. Perhaps he didn't catch many buses in the early days of bus deregulation when on busy routes you had far more buses running than before but if you wanted the cheapest one you had to let 3 others go past first, and funnily enough no operator at all ran on the less popular routes.

Good to see you back and repaired / recovering.   YOUR health comes even before GWR^▸ (Great Western Railway)'s position in the rail hierarchy ... including their way of inflating their mileage by being the "Great Way Round".  To this day, Taunton to Cardiff at 2 and a quarter hours on a through train to cover the less than 40 miles as the crow flies must be one of the longest diversions and slowest journeys in the UK^▸ (United Kingdom).    Just imagine what would be said if London to Tunbridge Wells ... or Rochester ...  or Haywards Heath ... or Guildford (similar distances) took as long 

There could be a very relevant recent reason for that.

I don't know any of the answers but I can add another short-lived service.  It's a station I never visited, though I did travel along the line in the 1980s.

15. The station featured two platforms linked by a footbridge, a waiting room, and a gravel car park. ... The structure used a scaffolding base covered by wooden planks with an anti-slip surfacing. ... Once opened, the station was served by all existing trains and an additional hourly shuttle train. ... This service started on 30 November 2009 and ran until 28 May 2010. It was initially funded by the Department for Transport at a cost of £216,000. All services between [deleted], [deleted], [deleted] and [deleted] were free of charge for this period.
