Could it be because train drivers wages are ridiculously high. Advertised in Cornwall last year for a GWR^▸ (Great Western Railway) driver based Penzance, which means basically driving SEMI-AUTOMATIC trains Penzance to Newton Abbot/Exeter [Like a really tough job!] - £47,000 per year start. That is absurd. It is more than many airline pilots earn on budget airlines after 5 years. Such a wage maybe warranted on stressful commuter lines & inter-city express routes although if you watch YouTube videos recorded by drivers in the driver's cab they don't seem too stressed to me. Also it staggers me that after 20 years of the internet there are still people who have never heard of booking in advance online to get cheaper tickets. Just beggars belief.
