"This part of EN 16186 applies to driver’s cabs of Electrical Multiple Unit (EMU), Diesel Multiple Unit (DMU), railcars, locomotives and driving trailers. NOTE 1 – This standard applies to rolling stock in the scope of the Directive 2008/57/EC." 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. For OTMs, see EN 14033 1 "deleted text" and EN 15746 1 "deleted text". This part of EN 16186 defines: - anthropometric data; - visibility conditions from the driver's cab, including forward visibility and the reference positions of line-side signals to be considered; - assessment methods. "NOTE 2 Due to railway systems constraints the level of visibility provided to the persons outside the defined anthropometric range may vary. It is up to the operator’s safety management system to address the potential restriction of front visibility, if the driver uses extreme seat positions combined with extreme body heights." "The actual seating and positioning habits of drivers regarding visibility, whether drivers are in or outside the range of anthropometric data of this standard is outside the scope of this document." "This standard is not intended to be applicable for tramways, metros and light rail vehicles."
