Agreed, although I wouldn't disapprove of that Headbolt service also coming down the Atherton line.The most DMU efficient option that isn't going to cause impossible levels of uproar is probably 2 Vic-Southport via Atherton and a shuttle to Headbolt from the bay, with 2 per hour via Bolton from NW as EMUs.
Could be timed quite well for the connection to/from Southport trains at Hindley (same platform), meaning no walking required.
If you were to run a shuttle on Headbolt services, either you need tight turnarounds at both ends (1 unit), or long turnarounds at both ends (2 units) since it's a 25 minute journey.
In theory with tight turnarounds and 2 units you could do 2tph (5m turnarounds), or maybe 1.5tph (45m frequency) with slightly longer turnarounds to better connect at Wigan.
