Now I've looked at the article the biggest point seem to me the
incredibly old-fashioned and space-wasting half cab design. That was out
of date when the Routemaster was new (the trolleybuses they replaced had
full width cabs).

Coming to this late, but I'm not convinced that the half-cab was
really dated when the first Routemasters were introduced. The first
rear-engined double-deckers came into production about the same time
as the first production Routemasters, so perhaps four years after the
prototype Routemasters were developed. Other half-cab buses continued
in production through most of the 1960s. Presumably the Routemaster's
designers believed (rightly, as it turned out) that conductor
operation would continue in London for some decades to come. In the
early 1960s the law didn't permit one-person operation of double
deckers, and there were proposals to fit trapdoors at the top of the
stairs of rear-engined double-deckers so that they could be operated
as single deckers at quiet times.

There were buses in the 1950s and 1960s with a full-width front
windscreen, but following the half-cab layout with the engine next to
the driver. This was purely a styling feature, not one which would
have made any more space available for passengers, and one which
London Transport, who were presumably keen on saving weight and
ensuring ease of maintenance, were probably sensible not to adopt.

So the layout of the Routemaster was undoubtedly traditional, but at
least when it was first introduced, surely couldn't have been
dismissed as 'dated'.

(Incidentally I'm happy to be told I'm wrong by anybody else who
should come along with more technical knowledge)

The AEC Q in both single and double-deck versions were around in the
1930s. Side-engined, of course, Other examples were the Maudslay ML
and the NGT in single-deck form, and various Midland Red prototypes
(S1-S5) with rear and then underfloor engines. London Transport
operated Q's on their services, along with the Leyland TF
underfloor-engined bus and the Leyland Cub CR rear-engined bus.

Oddly, the TF and the CR both had half-cab arrangements, with
entrances behind the front wheels. Maybe they didn't wish to frighten
the passengers.
