You'd have thought that city-centre to city-centre a train would work out as a faster option than a plane, anyway, with all the pffaff of traffic and airport procedures.
But the point about tickets being more expensive by rail than air is a sad and somewhat shocking state of affairs
The irony is that money paid for train tickets, these days, is broadly money that's within the realm of HM Government; I was chatting about an example of reducing
MP▸ 's travel expenses with a member our MP's team the other day and he was saying they try to book sensible in cost but have to be able to justify line by line expenses, so reducing fares by quirks of the system isn't on. On the other hand, they can't just get the simplest ticket if it's very expensive because the is seen against expenses, even is an a payment of £50 "over the top" would simply reduce the bottom line for the Treasury by £50 - different parts of the public purse but perception is important.
So - Network Rail staff flying? Slightly different case because the money's going for the most part to EasyJet, RyanAir or someone rather that all or most of it back into the public pot.
My personal thoughts are that people working on or advocating rail should lean towards rail where it's practical, and especially where it keep the money in the same purse that funds rail. So Network Rail staff should lean towards using the railway. As a demonstration to the public and also as a part of their "forever learning" and keeping up to date with things on the ground. HOWEVER that's a 'lean' and not an absolute and if it's prudent in both terms of staff member's time / cost and them having to spend nights away, then that's something that tips the balance.
Before criticising, I look at what I do. I wait for a train, but if there's not one available on a local journey and I can be home an hour or more earlier, I'll take a bus. If no bus I will call my SO and on promise of stopping and KFC on the way home, I'll get pick up at
WSB» . Where rail is absurd, I will take a bus or even drive or fly. Whitby to Redcar. Faro to Seville. Melksham to Catania.
