the second batch of trains, 38 three-car sets and 5 spare motor cars, used swiss oerlikon equipment and was generally similar to the siemens powered stock. the four traction motors were rated at and these trains seated 33 first and 130 third class passengers. the third class accommodation was a mixture of longitudinal seating and seats arranged in facing bays in pairs on either side of the gangway. the first class accommodation (downgraded to third class at the beginning of the second world war), occupied two of the three saloons into which the intermediate car was divided, on being for smokers and the centre saloon for non-smokers. the saloons were separated by swing doors with frosted glass or bevelled plain glass glazing, the latter having an etched lnwr script decorative monogram. the first class seating was in facing pairs arranged 2+1 on either side of the gangway, and the general ambience was edwardian-luxurious, with mahogany panelling. above the seats were glazed frames which displayed photographs of landscapes and towns served by the london and north western railway; these were retained to the end.
