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 1 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.
