Catenary systems need much more overhead clearance don't they? And
buses are not as desirable to passengers, are more costly in the long
run and can't meet the worst case throughput requirements can they?

are of London and New York systems respectively. Apparently Washington
DC was the only other similar system in the US. Looks like the
New York systems were phased
out in the late 40s and early fifties. Saw a note somewhere that the
hadn't changed since the turn of the century (1900). Maybe that
system was robust! I could only hope. Would be real cautious of any
ideas engineers had to improve on the subgrade support system, though
would hope something less expepensive than the deeply set, large cast
would be workable.
Does anyone know of any more conduit systems, especially more recent
What of installation costs? Available professional expertise?
