Hello there, the steam locomotive featured in the video is Kerr Stuart (Works No. 4034 of 1920 vintage) 0-6-2T Baretto Class No. 4 'Superior'. It should be noted that Excelsior is a Kerr Stuart 0-4-2ST Brazil Class and is painted in green. Excelsior is smaller than Superior. Best wishes and take care. Kind regards, Peter Skuce. St Albans. Hertfordshire.
