GB/T 5914.1-2015Drivers cab for locomotives -- Part 1: Visibility conditions (English PDF)

Foreword

GB/T 5914, Driver's Cab for Locomotives, is divided into two parts.

-- Part 1. Visibility Conditions;

-- Part 2. Position of Front and Side Windows and Other Windows for Driver's Cabs

of Locomotives.

This Part is the first part of GB/T 5914.

This Part was drafted in accordance with the rules given in GB/T 1.1-2009.

This Part partly replaces GB 5914.1-2000, Visibility Conditions for Driver's Cabs of

Locomotives. Compared with GB 5914.1-2000, the major technical changes are as

follows.

-- it changes the nature of the standard from a national compulsory standard to a

national voluntary standard;

-- it modifies the application scope and deletes "multiple units and new stock used

on international services" (see Article 1; Article 1 of GB 5914.1-2000);

-- it adds the normative references, GB/T 10000 and GB/T 12985 (see Article 2 and

3.2.2);

-- it deletes that "multiple units shall also carry two thirds of rated load" (see GB

5914.1-2000, 3.1.2);

-- it deletes "or multiple units" in GB 5914.1-2000 (see 5914.1-2000, 3.2.1);

-- it modifies the requirements and illustration for the reference position of the

driver's eyes (see 3.2.2; GB 5914.1-2000, 3.2.2);

-- it modifies the visibility requirements for high signals, changing the position

requirements from "10 m or more" into "10 m and more" (see 4.1; GB 5914.1-

2000, 4.1);

-- it modifies the visibility requirements for low signals, changing the position

requirements from "within 15 m" into "15 m and more" (see 4.2; GB 5914.1-2000,

4.2).

This Part was redrafted by referring to UIC 617-7.1964, Regulations Concerning

Conditions of Visibility from Driving Compartments of Electric Powered Stock, and UIC

625-6.1963, Regulations Concerning Conditions of Visibility from Driving

Compartments of Combustion-engined Powered Stock; this Part is non-equivalent to

UIC 617-7.1964 and UIC 625-6.1963.

Driver's Cab for Locomotives – Part 1. Visibility Conditions

1 Application Scope

This Part specifies conditions of visibility for each running direction along straight track

and on curves with a radius of not less than 300 m.

This Part applies to driver's cab of electric locomotives and combustion-engined

locomotives; this Part does not apply to driver's cab of shunting locomotives.

This Part can work as a reference for other rolling stock having a driver's cab.
