    The designer will have to consider a large number of potential constraints:

    - Axle-load that the track will take.
    -Total weight that bridge spans will take (or available cranes can lift).
    - Total length that can fit in shed/works, on turntables or in engine release roads.
    - Whether it will go round the curves - a major issue for a 12-coupled.
    - Loading gauge heights and widths.

    And no doubt other factors as well. All of these constraints may change over time.

    Have you fallen asleep on your typewriter, Andrew?

    That looks like of those photoshop jobs where someone takes a perfectly reasonable Loco and stretches it. (The clue is in the vast over-provision of domes - I mean, come on, how many do you need? ;)

    Perhaps someone with a CAD package could modify the Bulgarian design to incorporate a Bulleid MN boiler. The result would make an interesting comparison with "The Leader".

    Has anyone heard of progress on 7229 lately? The two seemed to be going gangbusters (relatively).

    I will happily stand corrected, but I believe the efforts we saw a while ago were only to get all the parts in one place....

    That sounds familiar. Maybe I was getting 00 and 29 mixed up. Which then means the 00 will be the first of the class to steam in preservation.

    I would suspect that 7202 at Didcot may be the first one to run. It's further advanced from memory.
