The cut to the 189 seems sensible - Arriva have taken a long time to turn their Yorkshire services in a pattern of certain key corridors running in relatively straight lines
The 140/141 provides a fifteen minute Leeds - Castleford - Pontefract service that is much simpler than the messy combination of services before (the 189 that ran Leeds - Castleford - Wakefield, the 411 that ran Leeds - Pontefract whilst skirting round the edge of Castleford instead of serving the centre, as well as various Castleford - Pontefract routes that required cross-referencing different timetables)
Same with the 268 being extended from Bradford - Dewsbury through to Wakefield a few years ago - one simple corridor
It feels like they are about twenty years behind the kinds of changes that First/ Stagecoach were making to bring their operations up to scratch in other parts of the country
But it's not amazing territory for bus operators, lots of similarly sized towns (people might travel from suburbs into the city, people might travel from outlying towns into the city, but with so many similarly sized towns there's not much need to go between them, or any demand is spread in several different directions, so it's harder to sustain a commercial bus service)
