So again why not add something constructive to the discussion.
Which lines are you referring to?
How many services are they missing?
How much of a negative impact is this having on passenger numbers from your personal observations?
If the decrease in passengers is proportional to the decrease in the level of service then it's not relevant in this context. I understand the Northern network isn't just Manchester and Leeds. I also understand in this context it probably is the biggest cities, that had the greatest commuter flows pre-COVID, that will have seen the biggest change in demand post-COVID.
Ok. To add to the discussion:-
Doncaster to Scunthorpe - Hourly train service replaced by Two hourly bus service
Sheffield to Doncaster (local service) Reduced by 2/3rds (two trains per hour reduced to two trains per three hours). Early and late trains cut.
Sheffield to York via Pontefract trains replaced by buses between Moorthorpe and York
Huddersfield to Wakefield/Castleford trains replaced by buses
Sheffield to Gainsborough stopping service basically withdrawn
Hull to Bridlington reduced from half hourly to hourly.
Doncaster to Hull stopping services reduced from hourly to 2 trains per three hours
Further reductions will apply to off peak services in May on a number of routes in south and west Yorkshire.
Although not totally relevant to this particular discussions ad hoc cancellations have been far higher on the East side of the Pennines
For example in the latest period 12.7% of services in South and East Yorkshire were cancelled. Today two consecutive Sheffield to Huddersfield trains are cancelled. This level of reliability will no doubt impact on passenger levels.
