So, what, where and why is the "Todmorden Curve" an important development in the area's rail network.
A press article from the Bolton News in May 2011 introduces the topic.
Faster trains could be running between Burnley and Manchester as soon as December 2013 after engineers gave their seal of approval to the project. Network Rail has completed a detailed assessment into whether the vital Todmorden Curve link could be reinstated. Its engineers say the project, which would cost between £7.5million and £8million, is feasible, despite complications over the exact route.
This means the only obstacle now is finding the cash.
The 500-metre stretch of track known as the Todmorden Curve, which has not been used since the 1960s, connects the Burnley to Manchester lines. Journey times would be cut to 40 minutes. Commuters currently have to change at Hebden Bridge, Blackburn or Preston, or use the Witch Way bus service, all of which take over an hour.
Burnley has a population of about 74,000 but, for the last 40 years or so, has lacked a direct rail link to Manchester, the capital of the north west (but don't say that in Liverpool!) only 21 miles away. The "Witch Way" bus (X43) runs every 15 minutes ...
But the journey time is not attractive at one hour and seventeen minutes. The route is heavily promoted ...
The offer of a reduction of journey time of nearly 50% (77 minutes to 40 minutes) looks too good to be true. The Todmorden Curve at £8 million seems like a real bonus for commuters, always heralded as the only travellers on public transport, but also for their oft ignored off peak and weekend compatriots.
And all this by December 2013!
It didn't quite happen that way, as we shall see. But we need to explain how big brave Burnley lost its link to Manchester.
It's a bit complicated and will manifest itself on Friday.
