    I thought I'd make this thread to help DTG to more accurately design and place the appropriate overhead line equipment (OLE), when building new routes. They said they want to get more things looking 'right' as well as being more accurate, which is where OLE falls short of in TSW.

    Now I don't expect them to design and model every single type, as there are hundreds, but it would be a start to place the appropriate type based on location and era, and not just place any old type.

    Below I will give examples of the different types of OLE designs and what lines you typically see them on.

    Common types of OLE:

    Classic designs and installations

    Name: MK3 Headspan
    Locations: MML South, ECML, GWML to Airport Jn, WCML North in selected locations
    [​IMG]

    Name: 1950/1960s portal (WCML)
    Locations: Predominantly on the full length of the WCML
    [​IMG]

    Name: 1950/1960s portal (other)
    Locations: GEML & WAML, C2C line, various Scottish routes
    [​IMG]

    Newer installations and designs:

    Name: Series 1 OLE
    Locations: Predominantly for all new electrification projects on the GWML
    [​IMG]

    Name: Series 2 OLE

    Locations: MML North of Bedford, recent electrification in The North, recent electrification in Scotland

    This is a well-timed thread.

    I am fully anticipating the arrival of a partial WCML London to Milton Keynes route, ported from TS2012 to TSW 2, perhaps re-using some of the assets on the Bakerloo Line route..... before the year is out..... ;-)

    (Just a guess)

    If they were ever to release a stretch of the WCML with the OHLE used from the Bakerloo route then it won't be a purchase from me, not even on a sale, would be a right immersion breaker - I can't be doing with it on the Bakerloo route but we don't get to see much of the WCML so I just about put up with it.

    Same here. The WCML has its own distinct look thanks to the 1960s OLE. If DTG recycled the GWE/BKL OLE, it’d just look so wrong.

    You do not find 1950/1960s Portal OHLE north of Weaver Jn until you reach the outskirts of Motherwell.
    When the WCML was electrified north of Weaver Jn in 1974 they used Mk3 Headspan OHLE Equipment

    Well done DTG for modelling a variety of new and accurate OLE for GCC and not just recycling what we already have :)

    I was wondering if the catenary on this route is accurately depicted... I'm glad that it is!

    It looks a bit clean and new looking so I’ll weather it.

    There still seems to be a a variety of models so I'll have fun with that. Note that I do not have to change each, individual gantry, so length of route is irrelevant.

    The GCC Gantries are virtually perfect (minus weathering).

    Yes, I'm so happy they modelled the correct ones as it is a big part of the route. I'll be weathering these accordingly.

    I want to go more in-depth into it to make it easier to understand

    TYPES OF CANTILEVERS
    upload_2023-1-31_20-27-26.jpeg

    Cantilever used on 2 Tracks: present on ECML in this type of design (MK3b East Coast, Midland Mainline and GWML from paddington to heathrow used as a modification of the MK3a on the WCML with slight design tweaks )
    upload_2023-1-31_20-29-14.jpeg
    West Coast MK3A OHLE: present on west coast mainline north of weaver junction, similar to mk3b on ECML with difference in cantilever design.
    MML/SCOT S2 catenary:
    upload_2023-1-31_20-30-52.jpeg
