Will it Run? Hornby Intercity 125 High Speed Train Repair

I bought a massive lot of British locomotives several months ago, this high speed intercity 125 was among them. Unfortunately the locomotive wouldn't run as something inside the motor was burning. Today I decided to try get see what was going on with it as repair the issue. The armature turned out to be in poor condition however I luckily had some spare parts laying around I was able to put inside it.
