Other innovations required by the strategy include trains running when they were needed, rather than to a fixed timetable, to help ensure passengers had the least crowded trains possible. This is a world where the customer – rather than operational convenience – is at the heart of the rail transport strategy.

The cigar is yours, sir!

750 loudspeakers at places like Taplow may lead to complaints of noise nuisance from nearby housing, might it not?

Each Elizabeth line station has over 50 km of communications cabling, 200 CCTV^▸ (Closed Circuit Tele Vision) cameras, 66 information displays, 200 radio antennas, 750 loudspeakers and 50 help points. All this technology needs to be fully installed, tested and integrated.

Earlier this year, our contractor Align (a joint venture of Bouygues Travaux Publics, Sir Robert McAlpine and VolkerFitzpatrick) engaged with local schools in Buckinghamshire, Hertfordshire and Hillingdon and asked students to put forward names of women who have made their mark on history through their achievements. Tradition dictates that in order to keep the tunnellers safe underground, tunnel boring machines (TBMs) are given a female name before they are launched. The women below were shortlisted and we now want you to vote for your favourite name for our machines.

Cecilia Payne-Gaposchkin
Florence Nightingale
Marie Curie

Agree, "preserved" does imply preserved in substantially original condition. The fitting of replacement parts is often unavoidable, but these should be reasonably close facsimiles of the originals.
Many steam locos can reasonably be regarded as being preserved in substantially original condition.

However considering the West Somerset Railway as an example, the infrastructure is definitely "heritage" and not "preserved"
Electric lights, and concrete sleepers, and other features are appropriate on a working railway even if not original.

Tricky one ... as it's Heritage I've moved it to "Preserved lines" which I should REALLY name "Heritage lines" though a number of lessons (such as staff forgetting routes really apply to all railways - heritage, national network and London / Newcastle city networks too.

Is there any other,  can just see a 44' 3" ramp would work at 125 mph
