top Spanish shipping officials have resigned after signing-off on dozens of new train carriages which ended up being too huge to fit thru tunnels.

Three years in the past, state rail operator Renfe, introduced plans to modernise the carriages on narrow-gauge commuter trains and medium-distance trains in the towns of Asturias and Cantabria.

But closing month a layout flaw used to be unearthed which meant any trains being constructed under the €258m (£227.5m) scheme would be too massive to pass through tunnels in various parts of the region.

Spain’s rail network was once constructed within the nineteenth Century, and has tunnels beneath the mountainous panorama that don’t match standard up to date tunnel dimensions.
