    The Aylesbury - London Marylebone line is a railway line stretching approximately 39 miles (46 miles counting the Princes Risborough branch) over half of the route goes over the London Underground Metropolitan Line from Harrow-on-the-Hill to Amersham.

    From Marylebone the line runs through a series of tunnels as far as Finchley Road, from where the line runs overground and runs parallel to the Metropolitan and Jubilee Lines. At Neasden Junction, the Chiltern Mainline to Birmingham diverges to the west, while the Aylesbury line continues north parallel to the underground lines. The line then joins the Metropolitan line tracks a few yards south of Harrow-on-the-Hill station and shares this track with the fast Metropolitan line services to Amersham from Baker Street. Beyond Moor Park the line to Watford diverges.

    Then from Amersham you’ve now left the area of London, running through the Countryside of Buckinghamshire.

    STATIONS:

    (LU) meaning London Underground exclusive station

    HARROW-ON-THE-HILL
    NORTH HARROW (LU)
    PINNER (LU)
    NORTHWOOD HILLS (LU)
    NORTHWOOD (LU)
    MOOR PARK (LU)

    ROLLING STOCK:

    London Undergrounds S Stock runs a majority of services in the timetable, between Chesham and Amersham as far as Harrow-on-the-Hill

    BR CLASS 165 DMU (CTN) (REUSED)

    This DMU would run the full length of the route and the Branch to Princes Risborough, Chiltern Services on the route between Harrow-on-the-Hill and Rickmansworth go non stop and don’t stop at any Underground Station.

    KEY LANDMARKS ON THE ROUTE:


    London Marylebone:

    The Terminus of the Chiltern Mainline and the main hub for all Chiltern Services

    Chesham:
    The Furthest London Underground Station from London, and the terminus of the Metropolitan Line


    Harrow-on-the-Hill - Amersham section:

    An Interesting section, and one of only places on the London Underground network where Underground Trains run on the same track as National Rail Services.


    CONCLUSION:

    In Conclusion, a route such as this would not only be a first in terms of Chiltern being in TSW, but also a case of killing two birds with one stone by Including the S Stock for Underground Services.

    There is a wide service variety, with short form services on the Princes Risborough Branch and long haul services between Aylesbury Vale Parkway and Marylebone.

    The Appropriate price for a route such as this would be £29.99, however, judging by what DTG did with NEC Stamford, by including the M8, it could be that this route would be £32.99 due to the S Stock and amount of stations.
