The difference between steam railways and banks is that steam railways are not backed by any taxpayers' guarantee - 'too big to fail' doesn't apply to them. mickpop rightly says that they must be run as businesses, but all I am saying is that the people who run them are usually people who have worked their way up from volunteering and have come to know their particular line, so know what they are doing. At least they are unlikely to draw the salaries and bonuses to which bank directors and executives think they are entitled, and they will not be taking the day's takings to the casino! Cheap offers would bring in extra passengers but there is a risk that people who would happily have paid the full fare will, not unnaturally, take up these cheap offers too. It's never as easy as it looks!
