This video from looks at the Class 101 3 car Diesel Multiple Unit in BR Blue/Grey from Hornby. This is a OO gauge model with the running number 101324 and would fit a layout set between 1976 and 1986. The video features a full review, some detailed information about the original prototype and several shots of the Class 101 on the layout. Apologies to those who are hard of hearing as I left the Deltic 9005 running in the background while recording this review, details of what I said are displayed in a ticker at the bottom of the video.
