The ‘secret’ train being tested in Shropshire that could revolutionise rural rail journeys

By running a low-weight, single-carriage train, it reduces wear and tear on the infrastructure and, therefore, operational costs.

The demonstration vehicle has 56 seats, which is said to often be more than enough for the shorter routes it's designed to run on. This would release longer, heavier trains, to be redeployed in busier areas where the extra seats and standing room they'd provide would be needed.
