    According to Wikipedia : "Using differential gearing to transmit the power, it was built as a 4-8-4 with the coupling rods connecting the centre four pairs of driving wheels. The coupling rods between the innermost axles were later removed, but as the four axles were driven by a single gearbox, it remained a 4-8-4".

    Make of that what you will.

    The one I was reading about was a modern one, when lower power is required it drops to one bank of cylinders. Which engine it was I can't remember

    I suspect you are talking about the new Bombardier 4-engine locomotive in which only the engines required for the current load / speed operation are powered : link at https://www.bombardier.com/en/media...rdierdeliverstraxxdieselmu.bombardiercom.html

    Cadillac tried something similar with one of their V8s in the late 70s, the idea was some of the cylinders stopped firing when the car was at cruising speed and it effectively became a V4

    From the Ford Media Centre
    "The 1.0-liter EcoBoost engine featuring cylinder deactivation technology will from early 2018 deliver reduced running costs for customers by automatically stopping one of the engine’s cylinders when full capacity is not needed, such as when coasting or cruising with light demand on the engine."

    Bentley Continental, that has (or had) a cylinder deactivation system where half the V12 shut down when not required.

    Thanks, but no. It wasn't multi-engines with engines switching in and out, it was an engine with cylinders switching in and out. Rather than monopolise the thread I should stop it here, and I apologise for distracting everyone!

    And at what pace? I’ve used the 68 hauled services out of Marylebone a few times, and the power gives them the pace to run turn and turn about with the units on the line.

    I used to have a Capri that did much the same thing ... a bit more randomly perhaps :D

    Was it cylinders switching out or valves being kept open whilst the spark plugs and appropriate injection cycle interrupted.
    This, I think, is a system used on Ford Mustangs on cruise.

    Nothing new under the sun.
    Reminds me of BR 10100 in 1950, designed by Lt. Col. L. F. R. Fell, but was scrapped in 1960 after a fire.
    Apologies for thread drift.
