Just thinking back to when I was travelling home from university most evenings in the late 1970s. I used to regularly take the 18.38 Waterloo service from Southampton Central to Basingstoke, and would often enjoy a coffee and hot snack in the buffet car, which I think was possibly an RMB in the 4-REP units? Someone more knowledgeable than me will know.
Anyway, as the train pulled in, one could see the beautiful polished cutlery, starched white tablecloths and menus propped invitingly against the windows of the adjoining motor open second, which was used as a restaurant car. Sometimes the chef would be leaning from the window, taking a breather and enjoying the fresh air.
Once on board, the coffee and hot snack in the buffet was always an enjoyable way to end the day, and the bar would be busy, functioning as a mobile pub for business travellers going back up to ‘the smoke’.
Very different times indeed!
