..........the key phrase there is "when electric trains start running".......at the current rate it could be the next generations problem.
Indeed - where's all the electricity going to come from?  Coal-burning power stations closing, Hinckley Point C still a way off, no sign of Severn Barrage being built...

oops.  My mistake.  As you were.

An update on wiring progress for those that don't regularly get to see it:

Airport Junction, Hayes to Maidenhead:
Real progress over that last couple of months.  All structures, booms and small parts fitted and probably around 90-95% of the main contact wires have been strung through to MP25 east of Maidenhead station, though there's very little of the ATF (Auto Transformer Feeder) installed as yet.

Maidenhead to Ruscombe (Twyford):
Virtually all structures and booms/small parts fitted and wiring has just started at the Maidenhead end.

Ruscombe (Twyford) to Scours Lane (west of Reading):
Significant number of structures fitted and more and more booms and small parts now getting installed.

These are truly boom times for, er, booms!

As an electrification engineer the last thing I want is booms ...........................

A few bright sparks have posted some rather shocking puns there.  Roll Eyes

Logged

William Huskisson MP (Member of Parliament) was the first person to be killed by a train while crossing the tracks, in 1830.  Many more have died in the same way since then.  Don't take a chance: stop, look, listen.

"Level crossings are safe, unless they are used in an unsafe manner."  Discuss.

Resistance is futile ! (unless more than one ohm)
Logged

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU (Diesel Multiple Unit) is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.
