Model of the Week – Ex-LSWR N15 King Arthur class – 736 Excalibur

Hornby N15 class 736 Excalibur (1)This week’s model of the week is another regular performer at Locoyard and a superb model (click here for its’ review).

Hornby N15 King Arthur Class 736 ExcaliburAlthough not the lowest numbered of its’ class, 736 Excalibur was the first and emerged from Eastleigh works in September 1918.  A product of the London and South Western Railway’s Chief Mechanical Engineer (CME) Urie; the N15’s proved more than capable of keeping to schedules set in the early part of their career, but as timings became shorter and higher speeds were required; performance inadequacies revealed themselves.

736 became 30736 at nationalisation in 1948.  It was only a BR locomotive for 8 years and was retired due to its’ age and withdrawn in 1956 and then scrapped.  It was replaced by BR standard 5MT 73081, which took on Excalibur’s name.  BR standard 5MT’s were nicknamed  “Standard Arthur’s” by their crews.
