Why the piccadilly to Heathrow , why not the District?

Nigel Pendse wrote: "Johnny Mo" wrote in message om 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. That's true now, but when this decision was made in the 1970s, all LU stock had wooden slatted floors. |
