For the passengers waiting on the platforms at Wokingham, the simultaneous arrival of two empty trains, neither of which they were permitted to board, must have been confusing. 707.004 on 5Q37, the 15:22 from Reading to Clapham Yard, passed 707.003 and 707.008 on 5Q61, the 14:10 from Clapham Yard to Reading, on 13 April 2017. The units were both on mileage accumulation runs, which involved stopping at every station and opening then closing the doors before continuing.
