Something I was wondering the other day , when the extension to Heathrow
airport was built why didn't they re-extend the district line to Hounslow
and beyond and divert the piccadilly to ealing? Why? Because district trains
are much bigger and so they would have been much more room for passengers
and their luggage rather than the pokey little tube trains on the picc.

Was there a good reason for not doing this given the benefits it would have
entailed for passengers with luggage?

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.
