So, at line speed, how many miles of third rail would be required how often to keep the b attery at least 75% charged? Or is that answer impossible?
Once at line speed trains require very little energy to keep them going due to the very low rolling resistance
Third rail
I doubt that it will be allowed.
Someone, somewhere, will have to "sign off" the design as being as safe as is reasonably practicable, whilst knowingly rejecting safer alternatives such as OHLE, or batteries throughout. That person could be at risk of criminal prosecution, maybe decades later, when a trespasser is electrocuted.
The
ORR» have not ruled out top contact third rail on new electrification.
There are a number of constraints, improved fencing,
NR» to look at the risks in station areas for which a scheme has been developed for station platform areas for the power in the conductor rail to be off when not required by trains. The main point the ORR want to see is management of the electrical risk to the general public and staff
