The benefit of using this as the standard width for railway tracks is that railways can easily achieve cross-border connectivity, enhancing the transportation capacity of railways and avoiding some unnecessary transfer and junction processes.
However, not all countries use the 1435 mm standard width. The two countries on the Iberian Peninsula each have their own railway track width standards.
The railway width in Spain is 1674 mm, which is a truly broad-gauge railway. There are many benefits to broad-gauge railways; firstly, the wider carriages make train travel more comfortable and also increase the transportation capacity of train carriages.
Whether used for passenger or freight transport, trains running on wider tracks can carry a greater total tonnage, thus having greater transport capacity.
Wider tracks are also more stable, greatly enhancing train safety and reducing the risk of derailment.
