The old standard DB S

its
replacement, the articulated class 423, 3 sets on a 15.5m vehicle


And exactly no overall change to the unit - a 3 car 420 is 67400 mm
long with 12 door pairs per unit - and 423 are 4 car artic also 67400
mm long also with 12 door pairs per unit.


I'd like to have seen 376s built like DB 423s. Far too radical for UK
national railways (or too German for Connex as was) and far too
innovative for uk.railway to ever accept such a device
