Agreed a very good tour. It was an interesting how difficult it is to run a train on todays fragmented railway. A whole list of different organisation had to be involved.
But doesn't that happen everywhere - and not just in Britain? Private companies, governments of all sizes, even charities voluntary organisations and political parties use outsiders - subcontractors, in a sense - for a lot of their activities. By now
BR▸ would have been just the same, with or without any privatisation.
Why? In some cases it makes industrial sense: for example a small local council can't afford the special machinery used for resurfacing roads because they can't use even one big machine full-time. Companies (including ones I worked for) said they outsourced IT or "facilities management" to save money, but did not appear to have costed the loss of service (flexibiliy etc.). In many cases I don't think it did save money in reality.
So I now think, in most cases, it's just a fashion - so it will go out of fashion again.
