The bottleneck will be at Handsacre Junction and through the Colwich tunnels. Assuming sanity prevails, and the Handsacre junction design reverts to the fast line, then we can expect 10tph from OOC/Euston - with 7tph north of Handsacre. The post Sunak train service specification is still being (re)developed, but roughly, is expected to be - 3TPH to Birmingham Curzon Street, 3TPH to Manchester Piccadilly, 2 TPH to Liverpool with 1 tph of these splitting at Crewe, with a 400m train to Crewe (assuming platform lengthening still proceeds) splitting with 200m to Liverpool and 200m to Preston, 1TPH to Glasgow and 1 spare path. The spare path was originally allocated to a Macclesfield starter, calling at Stoke and Stafford - but its quite likely that this path will be reallocated, given that paths north of Handsacre will be at a premium.
