ANNEX III STRUCTURE OF TYPE NUMBER Each type of vehicle shall receive a number consisting of 10 digits with the following structure: XX XXX XXXX X Category — Family (Platform) Incrementa number Check digit Subcategory Field 1 Field 2 Field 3 Field 4 Where: Field 1 (digits 1 and 2) is assigned according to category and subcategory of the vehicle type in accordance with the following table: Code Category Subcategory 11 Traction vehicles Locomotive 12 Reserved 13 Self-propelled passenger trainset (incl. railbuses) 14 Reserved 15 Self-propelled freight trainset 16 Reserved 17 Shunter 18 Reserved 19 Other (tramways, light rail vehicles, etc.) 31 Hauled passenger vehicles Passenger coach (incl. sleeping cars, restaurant, etc.) 32 Reserved 33 Van 34 Reserved 35 Car carrier 36 Reserved 37 Vehicle for services (e.g. kitchen) 38 Reserved 39 Fixed rake of coaches 40 Reserved 41 Other 42-49 Reserved 51 Freight wagons (hauled) Freight wagon 52 Reserved 53 Fixed rake of freight wagons 54-59 Reserved 71 Special vehicles Self-propelled special vehicle 72 Reserved 73 Hauled special vehicle 74-79 Reserved Field 2 (digits from 3 to 5) is assigned according to the family to which the type of vehicle belongs. For new families (i.e. families not yet registered in ERATV) digits are progressively incremented by one unit each time an application for registration of a vehicle type belonging to a new family is received by the Agency. Field 3 (digits from 6 to 9) is a progressive number incremented by one unit each time an application for registration of a vehicle type belonging to a given family is received by the Agency. Field 4 (digit 10) is a check digit determined in the following manner (Luhn algorithm or modulus 10): — the digits in the even positions of the basic number (fields from 1 to 9 counting from the right) are taken at their own decimal value, — the digits in the odd positions of the basic number (counting from the right) are multiplied by 2, — the sum formed by the digits in even position and by all the digits which constitute the partial products obtained from the odd positions is then established, — the units digit of this sum is retained, — the complement required to bring the units digit to 10 forms the check-digit; should this units digit be nought, then the check-digit will also be nought. Examples of determining the check digit: 1 — Let the basic number be 3 3 8 4 4 7 9 6 1 Multiplication factor 2 1 2 1 2 1 2 1 2 6 3 16 4 8 7 18 6 2 Sum: 6 + 3 + 1 + 6 + 4 + 8 + 7 + 1 + 8 + 6 + 2 = 52 The units digit of this sum is 2. The check-digit number will therefore be 8 and the basic number thus becomes the registration number 33 844 7961 — 8. 2 — Let the basic number be 3 1 5 1 3 3 2 0 4 Multiplication factor 2 1 2 1 2 1 2 1 2 6 1 10 1 6 3 4 0 8 Sum: 6 + 1 + 1 + 0 + 1 + 6 + 3 + 4 + 0 + 8 = 30 The units digit of this sum is 0. The check-digit number will therefore be 0 and the basic number thus becomes the registration number 31 513 3204 — 0. If the type examination certificate or design examination certificate covers more than one version of the vehicle type, each of these versions shall be identified by an incremental three-digit number.
