Train lasted only a short amount of time about as long as the fireball head was visible. Although bromsgrove has light pollution from near by sports facilities and motorways so I could only see it just after the head of the fireball had produced it. So it may of been visible for longer.
The train was a glowing one and was the same bright blue white colour as the head while visible. The fire ball seemed to be breaking up on contact with the atmosphere as well as there were a small number of fragments (approx. 3)
Terminal flash
Observation
Unknown
Remarks
Slight Fragmentation was occurring while fire ball was visible roughly three fragments broke off . Brightness seemed to increase as fireball disappeared but due to the levels of light pollution and also the distance between myself and the object I can not claim to have witnessed a terminal explosion.
