TRAIN operator First Great Western - now known as Great Western Railway (GWR) - saw the biggest fall in complaints year-on-year during the last quarter, it has been revealed. 

The firm saw complaints fall by 31 per cent for the period between April and June, according to the latest figures from the Office of Rail and Road (ORR).

Meanwhile, Virgin Trains West Coast has been named as the operator with the highest rate of complaints for the 11th quarter in a row.

The operator received 196 complaints per 100,000 passenger journeys.

This happens to be the same rail line on which Virgin has just launched automatic compensation for passengers whose journey is delayed by at least half an hour.

Second on the list was Virgin Trains East Coast with 142.3 complaints, giving Virgin an unwanted one-two.

Chiltern came in third with 102.2 complaints per 100,000, but also saw the biggest year-on-year jump in complaints (63 per cent).

While Virgin West Coast had comfortably the highest rate of complaints, the figure fell from 231.8 in the previous quarter, and is less than half what they were five years ago.

As of Saturday October 3, Virgin became the first company to offer certain passengers automatic refunds if their journey is delayed.

The offer applies to anyone travelling on the Virgin West Coast line who booked their tickets via the company app or website.

Up until this summer, all compensation was paid in vouchers.

The rail operator analysis does not include the non-franchised Grand Central and Hull Trains services.
