One third of Chiltern Railway's fleet of two car Class 168/3s, all on one train. 168327, 168322 & 168326 approach Hatton North Junction in superb evening light on 19 April 2018 with the 1R48 16:47 Marylebone to Birmingham Moor Street service. Already having a substantial number of two car Class 165s, and a few two car Class 172s, I'm sure Chiltern would have preferred some longer trains when they acquired the nine Class 170 that became their Class 168/3s in 2015. Consequently they often get multipled up, like this.
