You already have my response.
I do. Pretending it could still be reversed is, I’m afraid, a false hope. Better to accept the reality.
A new line from St Albans Abbey to Hatfield via London Colney is feasible. The new line would join the ECML south of Hatfield.
How do you define feasible? What environmental investigations have been done? Ground investigations? Alignment investigation, with an outline track design that doesn’t break the laws of physics? Timetabling development? Who has signed all of these off as ‘feasible’? Could you perhaps provide a link to a report from a reputable consultancy who has done this work?
And you didn’t answer my question. How do you expect to gain permission for a line that bulldozes it’s way through the built up areas of London Colney and Hatfield?
It's not via London Colney, as the original poster was suggesting.
The Alban Way is perfectly walkable these days, albeit with the odd road crossing, a narrowing at one point in St Albans by a housing estate, and going through the middle of a newish housing estate in Hatfield - doable walking or on bike, but requires some destruction for a train.
‘Some‘ destruction?
It goes right through 3 residential areas in St Albans, all of which would require demolition in part (look up Orient Way, Hansell Gardens, and Coach Mews on Google Maps.
at Hatfield, it runs through some houses to the west of the A1(M) (demolition required) then also has the A1(M) in the way, which took the formation just south of the Galleria. Then the Galleria itself is in the way, demolition required. Then through a densely populated residential area of Hatfield, which would require extensive demolition, and also rather annoy several hundred more people who instead of having a bike track the other side of the fence would have a railway.
My back of an envelope estimate is that to rebuild the Alban way as a railway, you would need to buy somewhere in the region of 3-500 residential properties, a few dozen commercial properties, and compensate another couple of hundred.
As a further point, the line was only ever single track. Making it double track would bring additional costs, something in the region of £50m - £100m per mile would seem to be a fair estimate.
There is zero chance of the Alban way ever being reinstated as a public railway.
I'm aware that the path goes a different way, thanks for the description of the path. How popular is the footpath?
Very. Used by thousands of people a day, including hundreds of school children to get access to their schools, of which there are four bordering the line in St Albans alone, two of which use the line as a means of access to the school itself.
