I was looking at some reviews for another railway last night and the recent negative reviews were from people who had been expecting steam but got diesel. Yes the balance may be shifting but for many steam is still the expectation Jon

It's not just those walking away- it will be the disappointing experience for a number who do travel, including people with advance bookings, leading to people not returning, negative word-of-mouth or reviews etc Jon

Basic thermodynamics. Whilst heat transfer in the boiler is reasonably efficient the open steam cycle used in a locomotive is horribly inefficient. A diesel engine has an efficiency in the order of 30% to 40% then there are transmission losses....
