TN2314 Iss 1

This technical note describes the standards associated with rail vehicle route availability (RA) numbers, and provides guidance on the application of those standards to new rail vehicles and existing rail vehicles where a modification changes their weight. 

This technical note has been produced because the precise method of determining a rail vehicle’s route available number has changed over time, with the result that some older vehicles, particularly passenger multiple units, may be incorrectly classified. This technical note aims to clarify the correct method of classification.
It is applicable to:

• rolling stock owners and leasing companies;
• railway undertakings;
• vehicle manufacturers;
• entities in charge of maintenance; and
• project entities.
