Source-derived summary

The UIC type X, Y and Z coaches are passenger coaches for international railway services that have been standardised in certain respects by the International Union of Railways (Union internationale des chemins de fer or UIC).

In 1961, types X and Y were defined in UIC Leaflet 567, the type Z followed subsequently. This standardisation was intended to give rail passengers on international services a standard level of comfort; in addition it was intended to simplify the maintenance of coaches when abroad. One of the standards introduced was the use of rubber corridor connectors on gangways instead of bellows.

UIC type X

The UIC type X was based on the express coaches developed after the Second World War by the Deutsche Bundesbahn (DB). These coaches were 26.4 m (86 ft 7 in) long and had doors at each end as well as compartments opening off a corridor as follows:

Twelve compartments each with six seats in second class

Ten compartments each with six seats in first class

Composite coaches usually had six second class compartments and five first class compartments

Type X coaches went into service in many countries, the largest numbers being deployed by the DB and the Italian state railways.

UIC type Y

The UIC type Y was based on French proposals for an international express coach (Schnellzugwagen). Important differences from the type X were its shorter length and greater number of seats in second class compartments. The coaches were 24.5 m (80 ft 5 in) long, the doors were also at the ends and a corridor coach configuration was standard:

Ten compartments of eight seats in second class

Nine compartments of six seats in first class

The French state railway, SNCF, had composite coaches, sleepers, dining cars and coaches with a luggage section built as part of the same series.

The Danish national railway, the DSB, operated three main types of coaches based on the type Y, the first class A (a total of 25 coaches), second class B (291 coaches) and the mixed class AB (20 coaches), from 1966 till they were replaced by modern train sets.

Editorial analysis

Why this record matters

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation.
