THE days of grabbing a snack on the train may be about to come to an end after another rail operator said it was to take its buffet car out of service.

Chiltern Railways has said it set to scrap its on-board catering service as early as Saturday.

The decision to axe the food and drinks service, which offers coffees and bacon sandwiches among others snacks, will affect all trains which operate between London Marylebone, Oxford and Birmingham.

In a statement the rail operator said it was doing away with the service because ‘too many passengers were bringing their own food on board.’ Spokesperson Nicola Clark said: "Following an extensive review, we are sorry to announce that as of 20 May, Chiltern Railways will no longer provide on-train catering services.

"This affects both the Espresso Bar on our silver trains and the trolley service that operates on certain long-distance services.

"Over time, increasing numbers of customers are choosing to purchase food and drink at the shops and cafes at our stations, this has led to far fewer people purchasing on board and the delivery of the service is no longer sustainable.

"Therefore, from 20 May, the service will no longer be available and customers should purchase before travelling."

Chiltern Railways, which recently expanded its service to include trains running between Oxford Rail Station and London Marylebone, is not the first rail operator to stop its on-board catering service.

Southern Railways took the decision in July 2015 to stop its on-board catering service altogether.
