Engines of the LNER: Gresley A1 and A3

(Rated G for General audiences, meaning people of all ages can watch it. This is a video discussing a piece of history from the London and North Eastern Railway.)
ALRIGHT!!! So here is the first episode of the new series, and we're starting off with a very famous type: Gresley's A1s and A3s. It's quite ironic that this video comes out literally 4 days after the design turns 100 years old. (The first one being outshopped on April 11th, 1922.) In a sense, the timing of this may be a little late, but you'll find it was hella worth it. (I hope.)
(Special thanks goes to Glenlow Works for assisting me on getting the info correct for this.
