Future-proofing the Borders Railway
Source: Ricp
No question that any new road-bridge or other structure is designed to allow for double-tracking in the future. This could eventually become another Anglo-Scottish route again from Carlisle to Edinburgh, so penny-pinching now will be as big an error as the original closure.
Compare this with the valiant effort made by the Bluebell Railway, where to get the scheme finished within a reduced budget, they have ended up with a single trackbed at Imberhorne, not a double tracked route, as it was back in BR days.
Design capability for double-tracking with the minimum of disturbance must be built in NOW.
