No one has yet noted there are legal differences between sub-surface
stock ( district line) and tube stock (picc). To put a district train
thru a single bore tunnel would require a whole new fleet. Tube (and
WAGN class 313) need lengthwise evacuation, sub-surface stock does
not.

Inter-car movement on the D stock seems no harder than on Tube stock,
so is that just a question of carrying a (longer) ramp in the cab?
Presumably the fire resistance is much the same in all UG stock.

The District's D stock is the only one that still has wooden floors. Hence
they still carry fire extinguishers in the passenger areas, whereas some
more modern (or refurbished) types don't.
