UIC wagon number
The UIC wagon number (previously wagon number) enables freight and passenger wagons to be clearly identified and contains important key data for rail traffic .
The wagon number is specified by the UIC and forms a common language between railway companies (EVU), infrastructure operators and the responsible government agencies.
A complete wagon number consists of 12 digits, the individual digits of the wagon number have the following meaning:
first and second digit: | Code for the exchange process (for locomotives type code ) |
third and fourth digits: | UIC country code |
fifth to eighth digits: | Category indicators |
ninth to eleventh digits: | Number of the freight wagon in the series |
twelfth digit: | Self-check digit |
Code for the exchange procedure
The code for the replacement process is since 1964, the first and second digit of the twelve-digit car number on the side wall of a railroad car. It was made binding for the member railways by the UIC and the OSJD .
UIC country code
The country of origin of a vehicle is determined with the UIC country code (almost exclusively included state railways). The owner is identified by a following letter code. At the beginning of 2006, the coding of the car numbers was changed.
Category indicators
The category codes, fifth to eighth digits of the wagon number, contain the UIC generic symbol and the technical characteristics of a wagon. The UIC generic symbols are made up of a “generic letter” (capitalized) and one or more “identification letters” (lowercase).
Class codes for freight wagons
The fifth digit of the car number encrypted and wagons in the genus letters
- 0
- Generic letter T → Freight wagons with an opening roof
- 1
- Class letter G → Covered freight car of the standard design
- 2
- Class letter H → Covered freight car in a special design
- 3
- Generic letters K, O, R → flat wagons with single wheel sets of standard design
- 4th
- Generic letters L, S → flat wagons with individual wheel sets in a special design
- 5
- Class letter E → Open freight car of the standard design
- 6th
- Class letter F → Special design gondola
- 7th
- Generic letter Z → tank car
- 8th
- Generic letter I → refrigerated car
- 9
- Class letter U → special wagons
The sixth to eighth digits encode the code letters
Class key figures for passenger coaches
The fifth digit of the wagon number encodes the generic letter for passenger wagons
- 0
- Post and private cars, as well as older sleeping cars of the CIWLT
- 1
- A - 1st class seated carriage
- 2
- B - 2nd class seated carriage
- 3
- AB - 1st and 2nd class coaches
- 4th
- Ac and AcBc - 1st class and 1st and 2nd class couchette cars
- 5
- Bc - 2nd class couchette car
- 6th
- Sleeper cars and cars of special designs
- 7th
- Sleeper cars and cars of special designs
- 8th
- Sleeper cars and cars of special designs
- 9
- Baggage cart
The sixth digit of the wagon number for passenger coaches encodes the number of compartments:
for post and private cars:
- 0
- Mail car
- 6/7
- Sleeping cars that have not yet been added to the international WL pool and have not yet been codified for the national park
with seating car:
- 0
- 10 compartments
- 1
- 11 compartments (only AB or B)
- 2
- 12 compartments (only B)
- 7th
- 7 compartments
- 8th
- 8 compartments
- 9
- 9 compartments
The seventh digit encodes the maximum speed:
- 0 to 2
- up to 120 km / h
- 3 to 6
- up to 140 km / h
- 7 to 8
- up to 160 km / h
- 9
- over 160 km / h
The eighth digit encodes the heating system.
Number of the series
The ninth to eleventh digits are the consecutive numbering of freight wagons of the same series.
Within the individual wagon types, one or more serial numbers are assigned to each freight wagon series defined by identical technical properties.
Example:
The DB freight car series 631 begins with the car number 21 80 990 3 900-8 and ends with the number 21 80 990 3 914-9. The freight wagon with wagon number 21 80 990 3 914 -9 is therefore the fifteenth wagon in this series.
Self-check digit
To calculate the control number according to the Luhn algorithm , the individual digits of the car number are multiplied alternately by 2 and 1 from right to left. Then the checksum is formed. The difference between the checksum and the next highest multiple of ten is the self-checking number. The self-checking number is added to the eleven-digit master number with a hyphen.
Example:
Car number: 31 81 665 0 286-0
3 1 8 1 6 6 5 0 2 8 6 Multiplikation mit 2 1 2 1 2 1 2 1 2 1 2 ergibt 6 1 16 1 12 6 10 0 4 8 12 Quersumme 6 +1 +1+6 +1 +1+2 +6 +1+0 +0 +4 +8 +1+2 = 40, nächsthöhere Zehnerzahl = 40 → Selbstkontrollziffer = 0
Example UIC decryption
Example for the decryption of a UIC freight wagon number:
Wagennummer: '''21 80 990 3 914-9''' 2 = Code Austauschverfahren → im grenzüberschreitenden Verkehr international auf dem Gebiet von nur RIV oder RIV und PPW einsetzbar 1 = Code Austauschverfahren → bahneigener Wagen mit Einzelradsätzen und festgelegter Spurweite 80 = UIC-Ländercode → Deutschland 9 = Gattungsbuchstabe → U 9 = aus Tabelle UIC-438 → zwei Achsen 03 = aus Tabelle UIC-438 – Kennbuchstaben → ikk 914 = Nummer in der Baureihe 9 = Selbstkontrollziffer Berechnung Selbstkontrollziffer 2 1 8 0 9 9 0 3 9 1 4 Multiplikation mit 2 1 2 1 2 1 2 1 2 1 2 ergibt 4 +1 +16 +0 +18 +9 +0 +3 +18 +1 +8 Quersumme 4 +1 +1+6 +0 +1+8 +9 +0 +3 +1+8 +1 +8 = 51 nächsthöhere Zehnerzahl = 60 → Selbstkontrollziffer = 9 (60 − 51 = 9)
When calculating, it should be noted that, for example, 8 × 2 (third column of the multiplication) results in the value 16, which then leads to a checksum value of 1 + 6 = 7. So you don't just add up the results of the individual multiplications.
Summary:
It is a railway-owned wagon with individual wheel sets and a fixed track gauge, which can be used internationally in cross-border traffic in the area of only RIV or RIV and PPW . The country of origin is Germany and the owner is DB AG. It is a special type U wagon with the characteristics of two axles, a low-loader platform, a loading mass of up to 25 tons and it is the fifteenth wagon of the same series.
In short: two-axle low-loader wagon (before 1951: SSt 111; from 1980 UIC generic sign Uikk, series 631) of the DB AG, load capacity 25 tons, can be used internationally.
Reading process
Since the numbering of railroad cars, the car number has been read visually. Up until now, no railway company has been able to read the wagon numbers automatically and with a sufficiently low error rate. With the OCR process , the error rate when reading the lettering (DB AG: straight standard font DIN 16 variant DB) is below 5% (1 out of 20). See also identification in rail traffic
