87546 and 98462 were two blue tender engines who visited Sodor.
The Railway Series
In 1923, two blue engines without names, only known by their numbers - 87546 and 98462 - were sent to the North Western Railway on trial. They were horrid engines and were very spiteful and mean to poor Edward, so the Fat Director decided to send them away.
According to Wilbert Awdry, 87546 and 98462 were horrid rude engines who were very mean and spiteful to the others.
It is unknown what type of engine 87546 and 98462 really are.
87546 is only seen in one illustration, where he appears to have outside cylinders and inside steam pipes. Although his wheel arrangement is unknown, it is known that he has at least two leading wheels.
98462, on the other hand, appears in three illustrations. In the first, he appears to have inside cylinders and steam pipes, however in the second he has outside cylinders with inside steam pipes and Walschaerts valve gear. 98462 appears to have either a 4-4-2, 4-6-0 or 4-6-2 wheel arrangement.
In the first illustration of Edward's Day Out, 87546 and 98462 are painted NWR bright blue with brass boiler bands. In the second illustration, 98462 has red boiler bands and lining.
- 87546 and 98462 are two of a number of background engines inserted into the Railway Series by William Middleton and C. Reginald Dalby. In 1963, a young reader from New Zealand named Ross wrote to the Rev. W Awdry asking who the unnamed blue engines from the Three Railway Engines were and if they were featured in other stories. The Reverend invented an explanation that they were rude engines on trial who were quickly sent away.
- 87546's and 98462's numbers appear to be fictional, as no other engines have carried them.
