This European standard gives design rules and guidance in order to ensure proper access@ lighting; seating and exit of the driver??s cab. The different dimensions are based on the anthropometric data defined in EN 16186-1. The corresponding assessment methods are also included in this standard. It covers the following aspects: ?? dimension and interior layout; ?? door access@ steps@ floor characteristics; ?? seats dimension and clearance; ?? interior cab lighting; ?? emergency exit; ?? marking and labelling. This part of EN 16186 applies to driver??s cabs of Electrical Multiple Unit (EMU)@ Diesel Multiple Unit (DMU)@ Railcars@ Locomotives and Driving trailers (Driving Coaches). NOTE 1 This European standard applies to rolling stock in the scope of the Directive 2008/57/EC [6]. For OTMs@ see EN 14033-1 [12] and EN 15746-1 [18]. This part of EN 16186 applies to driver's desks installed on the left@ on the right@ or in a central position in the driver??s cab. Due to cab space and resulting desk integration constraints@ desk layout can vary. NOTE 2 Due to railway systems constraints@ the level of comfort and accessibility provided to the persons outside the anthropometric range defined in EN 16186?C1 may vary. Usually the operators manage the potential restrictions@ if the driver uses extreme seat positions combined with extreme body heights. This standard is not intended to be applicable for tramways@ metro and light rail vehicles.
