Impossible Railways

YESTERDAY, 8.00PM

 Whether it’s Dick Strawbridge building a model railway across Scotland or Michael Portillo getting excited about the London Underground, these are high times on television for train enthusiasts. This new and engagingly nerdy contribution to the subject begins its six-part run by assessing how railways have blazed a trail for all manner of engineering feats. We take in everything from an inverted monorail system in Germany to the (rather less seamless) Crossrail project in London.
