Princess anne – the hybrid ‘princess royal’

13 min read

The un-named experimental turbine driven No 6202 ended its service days in that form in May 1950, but thereafter was rebuilt and named ‘Princess Anne’ on the second birthday of the Princess Royal.David Bradshaw considers the subsequent rebuild and the decision to abandon the hybrid locomotive after just 11,443 miles as a victim of the tragic Harrow & Wealdstone crash of 8 October 1952, whereas No 46242 ‘City of Glasgow’ would be returned to service.

Known to all as the ‘Turbomotive’ since its completion at Crewe Works on 29 June 1935 – two years and two days after No 6200 Princess Royal entered traffic as Stanier’s first Pacific, just over 1½ years after No 6201 Princess Elizabeth followed, and a mere four days before the first production ‘Princess Royal’ appeared – Swedish-inspired turbine-driven steam locomotive LMS No 6202 was the third of the LMS prototype Pacifics, and the most radical. With its mileage building, and nationalisation, a repaint in BR lined black and renumbering behind us, No 46202 passes Halton Junction with a Liverpool (Lime Street) to London (Euston) express in 1949. With finer ‘lines’ on the other side, where the forward turbine and control rods were masked by a lengthy casing along the full platforming, this right-hand side view shows the casing of the smaller reverse turbine ending mid-way along the boiler, which was far less attractive. Smoke deflectors mask part of the bulbous casing above where cylinders would normally be. Aesthetics aside, this deviation from normal practice was successful – No 46202 could match a production ‘Princess Royal’ in performance, and use less coal and water while it was doing it.

I don’t remember the date, although it must have been 9 October 1954, I recall reading the headlines in my father’s Daily Herald of the appalling accident at Harrow & Wealdstone on the previous day where, as a result of a series of coincidences and errors, the 8am Euston to Manchester and Liverpool service ploughed into the wreckage of a southbound express which had collided with a local train in the station. The result was 111 deaths and many more injuries. Since then I have been fascinated with the fate of one of the locomotives involved, No 46202 Princess Anne, the erstwhile ‘Turbomotive’ which was the train engine on the Manchester/Liverpool express and had only recently been rebuilt as a traditional reciprocating locomotive at Crewe Works and given the name of the Queen’s daughter.
