When the LM units first arrived, they had a map above the doors of the Northampton line, very useful. There were also at the carriage ends pictures of local scenes. Berkhampstead, Rugby and so on. The trains had two sets of doors in 1st class. You can still see the bulkhead were the second door has been removed. The 16 seats in the compartment behind the cab, were the smoking compartment of 1st class.
