I would like to correct the article regarding the number of seats on the new Brighton line trains (Argus, July 24) and clarify the true position regarding seating capacity comparisons.

The new, air-conditioned, four-coach class 375 trains ordered for the Brighton line each have a total of 242 seats, compared with 236 seats in the four-coach slam-door class 421 and 302 seats in the four-coach slam-door class 423 train.

The class 375 has, therefore, only 15 seats less per coach than the class 423, not 60 less as the article stated. The two-by-two seating has been ergonomically designed for maximum comfort and is to a standard seen previously only in first-class accommodation. Ten per cent of the seating in each train consists of priority seats which provide more legroom for taller customers and easier access for those with restricted mobility. This exceeds regulatory requirements.

Proper balance of space and capacity in trains designed for busy, peak periods as well as leisure travel is a necessary compromise. Wide vestibule areas and aisle space between the two-by-two seating makes for easier access and circulation of passengers at busy times than is possible in the present slam-door coaches.

Also, the new trains have wide, low-threshold sliding doors to provide customers with disabilities ready access to saloon accommodation and toilets large enough to accommodate wheelchair users. This is a significant and welcome improvement on the current slam-door coaches.
