The plan is Farncombe goes back to 2tph
But that adds an extra train between Haslemere and Portsmouth, which adds cost on a line that is bringing in nowhere near the revenue it used to, the peak travel demand providing the crew (and revenue) to run the off-peak service previously. That high volume of first class annual gold cards from Haslemere has gone and unlikely to return any time soon.
I understand the December 22 plan is an improvement to restore a half-hourly service to Portsmouth which the xx30 as now, the xx45 terminating at Haslemere and the xx00 as now to Guildford, then Farncombe, Godalming, Haslemere and all to Portsmouth.
It’s better spacing for Portsmouth than the current xx30/xx45 but doesn’t increase the cost base on the line as just effectively swaps the 1P and 2P paths at Haslemere.
