For a start, 'them and us' needs to go. Bob Crow talking of class war is a joke with some of the salaries are well into the 'middle class range'. This is the problem with the extreme black and white of ideological politics, many people who own their own business can often be on less than half the wage of say a train driver, yet Crow would paint them as the bourgeois 'we need to attack'. Likewise managers need to engage more with employees and other companies instead of 'empire building'.
Everyone in the industry should see it as a 'partnership', where 'can do' is the norm, not putting up barriers at every turn to make a point. Staff should should feel they have a stake, and mangers should be honest and open.
Next a modern, qualified, mobile workforce. Where qualifications where can be translated inside and outside the industry are the norm, openness in entry of new recruits and inside the industry. As I said if I want to become an HGV driver or airline pilot I can, subject to me passing the courses. (Eg

http://www.northlancstraining.co.uk/ etc) Yet there are very few, if any courses than allow people entry into the railway industry. Which means the same old companies run it, with the same old people, and the bad apples inside are not easily replaceable, which allows them to go on strike every five minutes. It also keeps them trapped in jobs, when they should be able to move inside and out of the industry with ease subject to their ability.
Next sensible performance incentives, would reward people that do well, not automatic block payments for everyone, and re-educate those that need it.
Until the government, industry and the unions change this, which is one of the root causes, nothing will change. Rail will not get the investment, indeed it may even contract as it will be considered an outdated, inefficient, inflexible form of transport where the people in it see it as a job for life rather than competitively meeting customers needs.
