# UIC wagon numbers

The UIC wagon number (formerly wagon number ) allows an unambiguous identification of freight and passenger cars, and includes important key data for rail transport.

The car number is specified by the UIC and provides a common language between Railway Undertakings (RUs ), infrastructure operators and the competent public authorities.

A complete car number consists of 12 digits, each digit of car number have the following meaning:

- 5.1 Examples

## Code for the exchange procedure

The code for the exchange process since 1964, the first and second digit of the twelve -digit car number on the sidewall of a railroad car. It was established by the UIC and OSShD binding on the member railways.

## UIC country code

The UIC Country Code the country of origin of a vehicle is determined ( included almost exclusively State Railways ). The owner is indicated by a suffix letter code. In early 2006, the coding of the car numbers has been changed.

## Genus ratios

The genus ratios, fifth to eighth digit of car number, include the UIC genus characters and technical properties of a car. The UIC genus characters are composed of a "generic letter" together ( very important ) and one or more " letters " ( lowercase ).

### Genus ratios freight cars

The fifth digit of car number encrypted for wagons the genus letters

- 0 = category letter T → wagons with opening roof
- 1 = category letter G → boxcar of the standard design
- 2 = category letter H → Boxcar special types
- 3 = category letter K, O, R → flat- axle wagons of standard design
- 4 = generic letter L, S → flat- axle wagons in special design
- 5 = category letter E → Open goods wagon of the standard design
- 6 = category letter F → Open Wagons in special design
- 7 = category letter Z → tank car
- 8 = generic letter I → refrigerator car
- 9 = category letter U → Sonderwagen

The sixth to eighth digit encrypted code letters

### Genus ratios coaches

The fifth digit of car number encrypted with coaches the genus letters

- 0: postal and private cars, and sleeper CIWLT
- 1: A - seating car, 1st class
- 2: B - seat car, 2nd class
- 3: AB - seat car, 1st and 2nd class
- 4: Ac and ACBC - couchette 1st class couchette 1st and 2nd class
- 5: Bc - 2nd class couchette coach
- 6: sleeping cars and cars of special designs
- 7: sleeping cars and cars of special designs
- 8: sleeping cars and cars of special designs
- 9: luggage cart

The sixth digit of car number at coaches encrypts the number of compartments:

- 0: Postwagen - ie 00
- 6/7: Sleeping car, which are not yet incorporated into the international WL pool and not yet codified in the national park - so 06 and 07

At A - Car:

0 10 compartments - ie 10 7 7 compartments - ie 17 8 8 compartments - ie 18 9 9 compartments - the equivalent of 19 in B-cars:

0 10 compartments - that is, 20 1 11 compartments - ie 21 2 12 compartments - ie 22 7 7 compartments - ie 27 8 8 compartments - ie 28 9 9 compartments - ie 29 with AB carriage:

0 10 compartments - ie 30 1 11 compartments - ie 31 7 7 compartments - ie 37 8 8 compartments - ie 38 9 9 compartments - ie 39 The seventh digit encrypts the maximum speed:

- 0-2 = Speed up to 120 km / h
- 3-6 = up to 140 km / h
- 7-8 = up to 160 km / h
- 9 = more than 160 km / h

The eighth digit encrypted the heating system.

## Number of series

The ninth to eleventh digit is the sequential number of freight cars of the same model. Within each type of wagon one or more serial numbers are allocated for each defined by the same technical characteristics freight car series.

Example:

The DB freight cars 631 series starts with the car number 21 80 990 3900-8 and ends with the number 21 80 990 3914-8. Thus, the wagons with the car number 21 80 990 3914-8 the fifteenth cars of this series.

## Self-check digit

To calculate the check digit, the individual digits of the car number are alternately multiplied from right to left with 2 and 1. After the checksum ( sum of digits ) is formed. The difference between the sum of the digits to the next higher decimal number results in the self-check digit. The self-check digit is appended with a dash to the eleven-digit root number.

### Examples

Car No.: 31 81 665 0286-0

3 1 8 1 6 6 5 0 2 8 6 multiplication by 2 1 2 1 2 1 2 1 2 1 2 results 6 1 16 1 12 6 10 0 4 8 12 checksum 6 1 1 6 1 1 2 6 1 0 0 1 2 4 8 = 40, next higher decimal number = 40 → self-check digit = 0 Example UIC decryption

Example for the decryption of a UIC freight wagon number:

Car No.: 21 80 990 3914-9 2 = code exchange process → the cross-border traffic internationally in the field of only RIV RIV and PPW or used 1 = Code exchange process → railway-owned axle wagons and fixed gauge 80 = UIC country code → Germany 9 = category letter → U 9 = from Table UIC -438 → 2 axes 03 = Table UIC 438 - Symbols → ikk 914 = number in the series 9 = self-check digit Self-check digit calculation 2 1 8 0 9 9 0 3 9 1 4 multiplication by 2 1 2 1 2 1 2 1 2 1 2 results 4 1 16 18 9 0 0 3 18 1 8 checksum 4 1 1 6 0 1 0 8 9 3 1 8 1 8 = 51 next higher decimal number = 60 → self-check digit = 9 ( 60-51 = 9) In the calculation is to be noted that, for example, 8x2 ( third column of the multiplication) gives a value of 16, which leads to a checksum value of 1 6 = 7. So not just the result of each multiplication together!

Summary: There is a railway-owned axle wagons and fixed gauge, which is used internationally in the field of RIV only or RIV and PPW in cross-border traffic. Country of origin is Germany and the owner is the DB AG. He is a special wagon type U with the properties of two axes, a low loading platform, a loading mass of up to 25 tons and he is the 15ste car the same series.

In short, two-axle low-loader wagons ( before 1951: sst 111; 1980 UIC genus characters Uikk, series 631 ) of the DB AG, load 25 tons, can be used internationally.

## Reading methods

Since the numbering of railway cars, the car number is read visually. No railway company had been able to read the car numbers automatically and with sufficiently low error rate. With OCR method the error rate when reading the label is (DB AG: Just standard font DIN 16 variant DB) under 5 % (1 of 20). See also identification in rail transport
