These are a 148th, N gauge model of a popular modern UK set of buffers. They are becoming widely used in terminal platforms of stations and are present in many new loco and carriage sidings. This model is based on a type used at Paddington Station and Manchester Airport among many places. The buffers fit neatly onto Peco N gauge track but should also fit most standard N gauge 9mm track.
Clean and prime before painting. I used IPA to clean, Halfords grey primer to prime and acrylic paints for top coats and detail. When clean and new they are overall red while the buffer lines are in white, the coupler protector in the middle of the buffer beam is grey metal with a black protector pad on the front surface and the clips onto the track are aluminium. Try google for source photos for colours - 'Manchester Airport buffers' or 'Paddington buffers'. I have not included the stop lamps as the support are very fine and vary from installation to installation.
These are also available in single items.
