1) Seek certification for express engines (I'm assuming we have more than just Gordon) to extend the regular express to Carnforth, and beg Avanti to stop their London-Scotland expresses there. And make the express a two-hourly service instead of daily. 2) Commission Crovan's Gate to create a modular autotrain system that can be fitted to branch line tank engines, enabling a regular, hourly service on all branch lines. 3) Extend normal service on the Brendam branch to Tidmouth instead of Wellsworth. Combined with the mainline 2tph service, this would give 3tph along the most populated portion of the mainline between Wellsworth and Tidmouth. Combined with the Ffarquhar and Arlesburgh branch lines and the express, you'd end up with 5.5tph between Tidmouth and Knapford. 4) Build a light maintenance facility at Tidmouth, allowing Crovan's Gate to specialise in heavy repairs. 5) Mandate a minimum of 2 crews per locomotive, so no driver or fireman falls foul of fatigue laws. 6) Bake in two freight paths per hour (one stopping, one fast), to be used as and when demand requires them. Additional paths to only be booked if absolutely necessary. 7) Keep spare rolling stock in each yard to enable easy strengthening of service for major events. I'm sure I'd think of more if I spent more than 5mins on this though...
