Having seen the Network Rail observation train a little earlier
at Witham station we looked at RTT and worked out where we would be able to see it working. We judged this to be at Hatfield Peverel and we calculated correctly. With 37402 'Stephen Middlemore 23.12.1954-8.6.2013' powering at the rear former Class 203 coach S60755 now numbered 975025 'Caroline' races through the station returning to Willesden where it had left earlier in the day at 07.25 travelling out via Cambridge and Ipswich.
