If it is possible for you to do so, please compare this photograph of 92134 with the previous view of 92214. Both were taken on Thursday 30th September 2021 showing 92214 on the 13:45 service from Loughborough to Leicester North with 92134, forty five minutes later, on the 14:30 service. See how much more effective the single chimney is in keeping exhaust clear of the cab, the train and the customers.
