Surely any former broad gauge line will take them
St. Ives?
Now let me think, It was 1892 when Brunels faster and more stable Broad Gauge was taken out of use.
In that 116 years a few civil engineer jobs have been done that have brought the Great western Regions line down to the more standard Loading gauge.
St Ives rebuilt 1970, Lelant Saltings Openned 1978, that stops 165/166 working the St Ives Branch, plus they would have to be brought down by road.
Devonport Station in Plymouth has had it's Platforms widened since 1892.
Plus all the Wooden Viaducts that were replaced.
