I’m not sure if I’ve seen it mentioned already but Brighouse when there are TRU works, gaining TPE services with a RRB connection to Huddersfield.
In forthcoming blockades the Huddersfield to Leeds and Huddersfield services will be combined to give Brighouse two Northern services per hour to Leeds and two TPE services per hour.
Doncaster gains calls on the Edinburgh to Plymouth services when they can’t go via Leeds.
I have seen in the past when Shipley/Guiseley to Leeds is closed the Ilkley to Leeds service is redirected to Bradford Forster Square, calling at Shipley but not Baildon and Frizinghall to allow a connection onto a RRB at Shipley.
There have also been Ilkley to Leeds via Shipley services in the past, meaning that Baildon has gained a direct Leeds service at the expense of a Bradford Forster Square service.
When the route through Wakefield Westgate has been closed the Knottingley to Leeds via Wakefield service has been diverted via Castleford, not calling at Glasshoughton and Woodlesford.
