37607 passes through Kemble station for the second time on 3 January 2019 with the 3Q64 10:20 Canton Pullmans to Canton Pullmans Network Rail test train. This was running 35 minutes early, having just reversed at Swindon. Why it was not held at Swindon until the booked time is a mystery, especially as it delayed the following 1G38 13:36 Paddington to Cheltenham Spa HST to such an extent that it had to be terminated at Gloucester!
