1926: The Ljungström locomotive was designed in Sweden. It differed
from the conventional Stephenson type in several ways. A turbine replaced
the cylinders and the exhaust steam was fed back into a condenser. A fan
was used to replace the action of the exhaust steam in creating a draught
through the boiler. The locomotive was articulated to the condenser unit
and the Whyte notation was 4-6-6-4T. Beyer, Peacock produced one engine for
British service and it ran extensive trails on the LMS and led, indirectly
to the "Stanier" Turbomotive..

In the discussion the President asked how these turbine locomotives
had performed in service. Mr. G. J. Carpenter said that the LMS had had one
which ran for about a year between St. Pancras and Manchester and between
St. Pancras and Leeds on express passenger and fast freight trains. The LMS
had made comparative tests between the turbine locomotive working at 300
lbf/in2 and a standard 2-6-0 reciprocating locomotive working
at 1801bf/in2. The fuel consumption of the turbine locomotive
was about 4% higher than than that of the standard locomotive, although the
turbine locomotive had performed very well. Mr. Carpenter went on to say
that Mr. Wood had mentioned a specific steam consumption of 11.55 lb/kW hr;
to what steam conditions did that refer? Mr. Wood replied that that the first
turbine had worked at 172 lbf/in2 gauge with 285°F superheat;
he thought the early turbo-generator would have used a similar supply. Mr.
Sheriff later enlarged on the reply to the President: the turbine of the
locomotive mentioned was, in fact, of the axial flow type but designed by
Aktiebolaget Ljungströms Angturbin (ALA). Several similar locomotives
were used on the Swedish State Railways from March 1921, mainly on the 400
mile Stockholm-Malmo run. The LMS example was built by Beyer, Peacock &
Co with an ALA axial flow turbine by the Brush Electrical Engineering Co.
The turbine comprised a number of blade wheels fastened together by a high
tensile bolt. The last blade wheel, that at the exhaust end, carried double
flow blading.
