It's the sections north of there that are now off the agenda yet again. Whats special about kettering compared to Nottingham and Derby which are much larger connurbations? Only that it's the junction to Corby. Frankly, they should implement one of those battery EMUs shuttling between Corby and Kettering - with charging wires at either station - and leave north of Bedford to diesels. At least until they can find the money to extend Thameslink to Leicester. A class 700 all the way to Leicester? Ouch! How far further north do you think Leicester is than Peterborough? By rail, I'd have thought it was nearly 20 miles further? Mind you, I wouldn't want to travel even as far as Peterborough on a class 700. |

Wed, 2 Aug 2017, Recliner remarked: A class 700 all the way to Leicester? Ouch! How far further north do you think Leicester is than Peterborough? By rail, I'd have thought it was nearly 20 miles further? Very close in mileage. For trains with a similar number of stops it's just 7 minutes. And that's with diesel on the MML, an electric train should be able to close the gap significantly. Mind you, I wouldn't want to travel even as far as Peterborough on a class 700. That's a different issue, but affects both routes. -- Roland Perry |

And that's with diesel on the MML, an electric train should be able to close the gap significantly. Or not, as the case may be: the current diesels can travel at up to 125mph, but the wiring to Bedford was only designed for 100mph running. And IEPs on diesel power probably won't be able to get up to 125mph. So if the HSTs are replaced by IEPs, the service may actually slow down. Mind you, I wouldn't want to travel even as far as Peterborough on a class 700. That's a different issue, but affects both routes. Indeed so. |

I suppose the DoT would argue the better acceleration of the IEP will make up for it but I suspect thats unlikely over longer distances. -- Spud |

I suppose the DoT would argue the better acceleration of the IEP will make up for it but I suspect thats unlikely over longer distances. Better acceleration under the wires, yes, but not on diesel north of Kettering. So you have three zones: 1. SPILL to Bedford. Already electrified, but only designed for 100mph trains. There was a project to upgrade it for more, faster trains, but I don't know if that project will continue. If it doesn't, IEPs will have good acceleration, but lower top speeds than the old diesels. 2. Bedford to Kettering. Newly electrified, suitable for 125 mph electric or diesel trains. IEPs will outperform the existing diesels. 3. Kettering to Leicester and on to Derby, Nottingham and Sheffield. Electrification work started, but work will be suspended indefinitely. Bi-mode IEPs will be able to run, but performance will be worse than current diesel trains, specially the Meridians. |

MML electrification was only cancelled ten days ago. -- Roland Perry |
