of Railway Locomotives and multiple units in Malaysia.
The current classification system was adopted by the then Malayan Railway in the 1940’s and was originally as follows:
|10-14||Diesel railcar trailers.|
|15-19||Diesel shunting locomotives.|
|20-24||Diesel main line locomotives.|
|25-29||Steam & Diesel railcars (motor cars).|
|30-39||Steam shunting locomotives.|
|40-49||Steam tank locomotives for main line work.|
|50-99||Steam tender locomotives.|
that numbers 1-9 were not used.
Due to the phasing out of steam and introduction of electric traction the
above system has altered over time. The original steam railcars were classes 25
and 26, while the diesel railcars were classes 27 and 28. Classes 25 and 26 are
now used for main line diesel locomotives while the electric multiple units are
all in class 8.
All the above classes have sub-classes for different manufacturers or
batches of locomotives/units. These use the numbers 1-9. Finally each locomotive
or car is assigned an individual running number of 2 digits.
As an example, there are 2 batches of the class 25 locomotive. The first
batch of 12 is numbered 25101 to 25112 and the second batch is 25201 to 25205.
There were 3 batches of EMU delivered in the 1990’s for the KTM Komuter system
– all were classified as 8 with sub-classes of 1, 2 & 3. The cars with
driving cabs have a prefix C while the trailer cars have a prefix T. The numbers
of the individual cars are thus C8101-C8136, T8101-T8118, C8201-C8244,
T8201-T8222, C8301-C8344 & T8301-T8322. These numbers are carried on either
side of the cars. In addition each multiple unit has a unique number on each
end, the class 8/1 being EMU01-EMU18, class 8/2 EMU41-EMU62 & class 8/3
Multiple units are made up of individual motor cars and trailer cars. In
general steam railcars had a motor car with a steam engine in a compartment at
one end and they were able to haul extra trailer cars or goods wagons if
required. Diesel multiple units tended to have a motorised car at either end
with trailer cars in between. Electric multiple units tend to have powered axles
or bogies on some or all the cars that make up the unit, as do modern diesel
multiple units. Multiple units normally run in fixed formations of 2 or more
cars with a driving cab at either end of the formation. If longer trains are
required 2 or more multiple units can be joined together.
The electric multiple units of the Malaysian Komuter system are 3-car
fixed formation units that normally run in pairs, making a total of 6 cars. This
would give a total train length of around 400 feet.
