*X20 built as three four-car sets.
*X21 is the other original series, and built as ten two car sets, with a less powerful motor.
*X22 was the result of four X21-units being rebuilt in the 1980s with a more spacious interior and more first class seating.
*X23 was created in 1991 after a number of accidents had put parts of the stock out of commission. It had three cars, but the same power as a X20 unit.
