i too hold full AC and DC PTS, and regularly drive over / under both systems.
3rd rail is distinctly 'lo-tech'. the main day to day operational difference between the systems is that one slip can more easily be fatal in 3rd rail areas, ohle is out of the way. and ohle is more energy efficient, it's proven that high voltage/low(ish) current transmission is less 'lossy' than high current/low(ish) voltage. I too read papers and watch news, up here in the merseyrail third-rail area there are regular incidents. and dead badgers. maybe such incidents don't make the news down there.
roll on fuel cells.

Look at the examples of 1980 EMU
The pantograph produces a wonderful buzzing noise
Third rail CAN use AC.uktrain225 said:OHLE are no limits.If it use third rail, it only supply DC.If the trainis AC motor,It have to use VVVF!If OHLE,it can supply DC or 25kV AC.so use OHLE is better.
