They then curtailed them to run south of the river only as the 73/74 and then not long after came up with the 2 series.
Even they were changed and butchered up before we see what we have now.
I can't remember when the X2 was axed (maybe it coincided with the arrival of the first lot of B9's on the X1).
The X2 was axed when the 2A/2C were introduced wasn't it? With the X1 going every 10 minutes too?
