From Professor Lewis Lesley, 1 Mar 2023:
So back to ‘first principles’ led to premature failures and replacement. One of my former students is now Operations Director of a major German tramway, where costs are about £10m/km for building robust double track tramways complete with electrification and stops. The LUAS in Dublin learnt from French experience, 30 new tramways in about 30 years. The criticisms of the NAO Report on UK tramways are still not fully appreciated, discussed my “Light Rail Developers’ Handbook”.
