On my visits to Ely, one of my favourite trains is the Hoo Junction to Whitemore Yard Departmental service. This can be anything from a light engine(s) to massive trains of engineers stock, including cranes.
These trains are usually hauled by Colas 66’s, but Colas 70’s are also used on occasions. Colas do not have many 66’s and only two of them have names. When Bachmann brought out the Colas 66, I purchased two. I then purchased Railtec transfers and Shawplan nameplates for 66849 and 66850.
In real terms this is not a complicated conversion and after removing the original numbers, the transfers and plates were added. Like all my loco’s I detailed the end with the driver and left the tension locks on the other. They will be lightly weathered later.
