This incident should remind us how vulnerable the railway is to incidents at critical points. Places like this need solutions before we start throwing cash at reopening long closed lines. Like at Castlefield the restricted geography dictates very expensive options. Like in Manchester some very extensive civil engineering is the only way to bring relief. River below, road to one side, tram and hill to the other - and a mockingly close railway heading across at too acute an angle to make a connection towards Penistone. Some sort of tunnelled tracks below Park Hill may be needed.
^^ This, this THIS! ^^
There needs to be more enthusiasm for sorting out the basics.
"simple" problems like this don't necessarily have "simple" solutions but we need to have a better everyday railway before we can get the crayons out and more on to the "nice to have" stuff
The Stoppers can only use 2C at Sheffield at the minute due to needing to keep 7 free for other trains. 2C of course can only fit two cars...
2C is a real problem - the Hope Valley services need longer trains at certain times of the week (from the Sheffield end, of course some quiet services at the Sheffield end were/will be busy services at the Manchester end, given the long duration of the Hope Valley stoppers and the fact that the Sheffield train is just an everyday commuter train at the Piccadilly end)...
...but longer trains means not being able to use the southern end bay (2C) which then means occupying one of the limited number of through platforms at Sheffield, or competing with the London "semi-fast" for the other southern bay (7). Longer London trains may mean that the days of the semi-fast using 7 may be limited, but then that causes other problems (given that, for a long time, the "semi-fast" had to run up to Woodburn to get out of the way for best part of an hour - which meant using a couple of paths in the northern throat as well as blocking the Lincoln line, which now has the addition of the Gainsborough service).
No easy solution - there may be some who'd suggest turning the Hope Valley stopper into a through service, e.g. onto a Doncaster stopper - but the Northern network is already crippled with unreliable services that are too long in duration so I think that it'd be a backward move (even if it did mean through Meadowhall trains for Hope Valley residents and a through train to the Peak District for the good people of Rotherham/ Donny).
