I think I can see why although this is based off TTD the principles are similar to real life. Basically, with two platforms, trains are able to pass each other on the crossover so there are two simple entries and exits a lot of the time. With three platforms you have more trains competing for the same space and if you only have one crossover to serve all three platforms the space is limited and therefore trains cannot pass each other so easily.
Or should I not base my assumptions on a computer game?

The same can't be said about the trains that reverse at North Greenwich. Stratford needs all it can get in the evening peak, but this is more than Stratford can handle iirc Surely Stratford with 3 platforms should be able to handle the same number of trains as Brixton does if not much more! No. Brixton has a high speed approach, allowing for faster platform re-occupation times (? <80secs). Stratford has slower speed approaches due to track geometry and dead end platforms, with slower platform re-occupation times. Having 3 platforms does not really increase capacity compared to 2, however it allows for more reliability as 2/3 movements can be parallel instead of 1/2. Whilst Brixton can now handle 33-34tph, I would expect that 30tph would be difficult to achieve at Stratford.

Expressions of interest now being sought for up to 18 trains for Jubilee Line and 50 (!) for the Northern Line. ITT to be issued early 2015. Global rail news articleThe contract for the construction of the Battersea Extension to the Northern Line is due to be signed on 2 September (see Finance and Policy Committee meeting papers on TfL website). This is ahead of the TWAO being granted sometime in the Autumn.
