The classification of a coach begins with one or more class letters, in our example above, a capital B. It describes the general class of coach:

The following lower-case letters follow the main letters and describe the technical equipment and fittings of the coach. How the letters are used, is at least partly up to the individual railway company. This overview is based on the system used by the Deutsche Bahn AG:

i

formerly: InterRegio coach

l

regional-traffic passenger coach (Regionalverkehrswagen) with length of more than 24.5 metres, centre aisle in 2nd class, centre aisle or side corridor in 1st class, rubber gangway connectors (currently not used)

The Austrian Railways use different secondary letters for twin- and four-axled coaches. The following letters have been in force since 1981. The letters d for double-decker coach, l for push-pull coaches and s for driving cars are written after a dash (e.g.: Bmpz-ds).

In addition to secondary letters, SNCF includes superscript characters to indicate the number of compartments or sections within a coach. (Example = A⁸tuj)

The Swiss Federal Railways currently uses secondary letters for their fleet of Eurofima coaches and to denote special type carriages.

The fifth digit of the Coach number defines the type:

• 0 = private coach
• 1 = first class seating coach (A)
• 2 = second seating class coach (B)
• 3 = mixed classes seating coach (AB)
• 4 = first or mixed class couchette coach (Ac, ABc)
• 5 = second class couchette coach (Bc)
• 7 = sleeper coach (any class)
