Full title and description

GOST R 50850-96 — "Вагоны метрополитена. Общие технические условия" (Metro coaches. General specifications). The standard establishes general technical requirements, parameters, dimensions and test/acceptance rules for metro (subway) rolling stock designed for operation on metro lines.

Abstract

This national standard defines the overall technical specifications for metro passenger cars (motor cars with driving cabs, intermediate motor cars, and unpowered trailers) including definitions, principal dimensions and parameters, design and strength requirements, braking and traction performance, noise and vibration limits, ventilation and illumination norms, safety and ergonomic provisions, and test/acceptance procedures. It includes normative references to related GOST and design documents and has undergone later amendments.

Scope

The standard applies to metro passenger cars intended for operation on metro lines designed according to applicable construction norms. It covers general technical requirements for new and modernized cars of the 1520 mm gauge system used in Russian and comparable metro networks, including structural, mechanical, electrical/traction-related performance, passenger capacity definitions, environmental and human-factor requirements, and the tests required for acceptance and certification.

Key topics and requirements

• Definitions of nominal and maximum passenger capacity and related load assumptions.
• Main parameters and dimensional tables (overall dimensions, wheelbase, axle loads, tare mass limits, seating capacity ranges).
• Strength and structural design requirements for car bodies and bogies; static and dynamic load limits.
• Braking and traction performance criteria, including test methods for acceleration, braking distances and emergency/parking brake effectiveness.
• Acoustic and vibration limits for passenger saloon and driver cab, and ventilation/illumination minimums.
• Fire-safety and materials requirements for interior finishing, plus requirements for signage and passenger information placement.
• Acceptance, type and certification test procedures to be performed during production and commissioning.

Typical use and users

Primary users are metro vehicle designers, manufacturers, testing laboratories, certification bodies and metro operating organizations responsible for procurement, acceptance and in-service compliance of rolling stock. Secondary users include national regulators, infrastructure owners, maintenance organizations and consultants involved in metro vehicle modernization or interoperability projects.

Related standards

The document references and is used alongside a range of GOST and industry standards covering: vehicle axle and wheel specifications (e.g., GOST 30237, GOST 30272), vehicle clearances (GOST 23961), human-machine interface and ergonomic requirements (GOST 21889, GOST 22269), and other technical normative documents for materials, welding and testing. It sits within the broader corpus of rail and rolling-stock GOST/R standards and related technical regulations.
