Hi,
i have just read that the max distances for the above track is:
s=600m
d=2700m
is the above roughly correct?
the reason i ask is this, (talking AC TC only)
single rail tracks are primary choice for long stretchs of plain line.
reduces IRJ's and keeps traction guys happy.
single rail TC are serial bonded, which is preffered.
double rail TC are used over point work where parrallel bonding is needed.
(im thinking all point work must be parralel bonded, is this correct?)
it doesnt make sense to me that the TC to be used on the long stretches of line is limited to 600m while the double rail TC, which is to be used only through junctions is acceptable up to 2700m.
does anybody know why there is such a big difference in single v double distances?
as for bonding, i have not got a full understanding so feel free to point out mistakes.
thanks
