I know the service pisses you off, but Jagman speaks the truth - the problem is that we sold off all the profitable sections of the rail network - after all, who would want to buy the services that run at a loss? To sell the less attractive routes we agreed to subsidise the privatisation. So now we see very little of the profits, and pay through the nose to cover the losses of these private companies.
Meanwhile, they make a profit and who does this go to? The management. Then when workers are unhappy at their conditions, they strike, and management makes people like you somehow believe that the unionised workers are the bad guys!! These guys aren't demanding bentleys and country estates like the management live in, they are demanding wages reflecting the work they do, in the conditions they do them, and the regional average salaries for the areas they have to live in so that they can work in these locations.
The problem is that media is controlled by men with money, so the papers report that stiking workers are the bad guys, and that they're causing problems for you, the Citizen. But that's not the case. The Management want to maximize their bank balances, at the expense of their workers living conditions.
AS for the service being crap? Expect it to get worse as networks get further privatised. Unprofitable services, like sunday services, out of hours services, services to more remote locations, non-rush-hour services will all be minimized, if not cancelled entirely.
