I went by Wembley Yard yesterday, Sunday 17th, at about 1115 and again at 1545 and I am sure I saw 4 or possibly 5 Class 67s in at least 4 different liveries. The only number I saw was 024 coupled to another in a brown and cream paint job.
I can well believe it; for a small class all delivered in a single squadron scheme they now exhibit quite a range of liveries:
EWS Red & Gold (As delivered, now 67007-009, 011, 016/017, 019/020, 022, 030)
DB Cargo Red (67004/010/013/015/018/028)
Royal Train Burgundy (67005/006)
Wrexham & Shropshire/Chiltern Grey & Silver (Originally 67010, 012-015, now 67012/014)
Arriva Trains Wales Dark Blue (67001-003)
Transport for Wales Light Grey (67025, more to follow)
Pullman Umber & Cream (67021/024)
Diamond Jubilee Silver (67026)
DB Executive Train Silver (67029)
Colas Rail Orange/Yellow (67023/027)
In addition, 67004 and 010 have carried Caledonian Sleeper midnight teal livery but have since been repainted DB red.
