UIC/ERA Railway Numbering Information
The UIC/ERA's European Vehicle Number (EVN) and
Vehicle Keeper Marking (VKM) classifications
are used to provide a unique international railway vehicle identifier. The classification
system format comprises the numeric EVN (below), e.g. "91 81 1044 246-7" and the
alpha VKM (e.g. "A-OBB").

How to use this EVN ID Form
This form can be used by Railway Modellers to generate UIC identifiers. The form
has data for motive power only (e.g. diesel, electric, steam locos, DMUs and EMUs).
1. Input loco's Interoperability/Tractive Mode (a), Country (b), and Keeper/Operator
(d) using the list boxes. Then enter the Country's power type in (c), e.g. a German
electric is '6', OR select 'Germany: Electric = 6' from the 'Power Type' list box.
2. Enter locomotive class and serial no. e.g. 186 243 in fields (d) & (e). NB: put
1st digit of any 4-digit class number in field (c).
3. Click 'Generate EVN-VKM ID' button: it executes and displays the check-digit
algorithm. The full UIC EVN-VKM numeric identifier (including check-digit)
and Keeper/Operator alpha code is generated in the yellow panel.
