Nottingham City Transport 401 (11.03.2021)

Last seen yesterday was this masked bio-gas bus for the 6 when it was on the school extra purple 87 run and, while it wasn't on the 6 yesterday, it was today and this is its first appearance on the route since 30th January, so gosh knows what happened to it but a return was coming and I decided to not let it evade me any longer when I saw that it was out on the road on its own route in the 6! 401, complete with mask, is now seen on Bridgford Road with a 6 to Edwalton.
