Punctuality on First Great Western's Thames Valley services improved in the past month, but still fell well short of the rail firm's targets.

After recording just 64 per cent of weekday rush-hour services as on time over the four weeks to January 6, FGW said 78.2 per cent of trains in the area were on time in the following four weeks to Sunday, February 3.

The firm's punctuality target under its Passenger's Charter is 92 per cent.

As a result of the target being missed, season ticket holders will get a 10 per cent discount.

On the firm's long-distance services, 83.7 per cent were on time. The target is 90 per cent.
