Tail of Tokyu Oimachi Line 6000 Series Train
Tokyu 6000 series cars have serial numbers like “6XYZ.” The first “6” is the series number. The second digit means the car number: car No.1 of a train has serial number 61YZ. The last two digits mean the number of the train: the cars of the first 6000 series have number like 6X01, the cars of the second 6000 series train have numbe like 6X02, and so on.
When a 6000 series was extended to a seven-car train, there were two possibilities concerning the serial number. The first possibility was giving number “67YZ” to the inserted car, and do not change numbers of the existing cars. The second possibility was giving number “63YZ” to the newly inserted car No.3, and renumber the car No.3, 4, 5, and 6.
Tokyu chose the second way. The train in this photo has number “6703,” and an erased “6” is visible under “7.” The replacing work seems to be quick-fix. The font of “7” is a little different from the others: the other digits have red shadow, but “7” does not.
Renumbering the serial number may make some problems concerning maintenance, because there are two cars that had number “6303.” It seems that Tokyu Corporation has another system to identify a car.
