Nottingham City Transport 638 (21.08.2025)

Following on from the withdrawals of 930-932 from the Uni 4 route, the three navy spare E400's have now been given the Uni 4 branding to replace them. 638 in its slightly modernized navy line livery is seen in West Bridgford with a 9 to Wilford Hill in place of a usual branded Yutong E10.
