Waste of money, at 28 years of age they should be pensioned off and sent for recycling. I no longer use the train as the abysmal third-world conditions on the Portsmouth - Cardiff route just aren’t worth the money. I can’t see any reason to pay ridiculous amounts of money to be deafened, overheated, frozen (depending on the time of year), subjected to toxic fumes and the dubious sticky substances found in these rattling mobile Petri dishes.
My car is cheaper, quieter, climate-controlled, relaxing, hygienic and often quicker.
Unless the refurbishment includes a totally new interior, a completely new air-conditioning system, new tinted double-glazed sealed windows, a new exhaust system and some serious sound deadening, anything less is just squandering good money after bad.
