Boris was one of the three LNER A0's that were built in 1922.


Boris was built in Doncaster in 1922 as one of the three prototypes of the LNER A1/A3 Class known as the A0, which included modifications such as a larger boiler. The other two were Gordon and Jeremy.

The following year in 1923, all three A0s has passed most tests and were ready to head to their new homes. Gordon would be sent to the Island of Sodor, Boris said to him that it was nice to know him and that now he should bring the Doncaster pride into Sodor.

It is likely that Boris was put to work on the LNER after his tests were completed. Given that all the LNER A1/A3 Pacific class locomotives except for the Flying Scotsman were withdrawn from service scrapped between 1959 and 1966, it can be assumed that he was as well.


Unlike Gordon and Jeremy, who were painted in LNER Apple Green when the were first built, Boris was painted in a special black coat. This color would eventually be used on most LNER locomotives during World War II.
