A / B / C Exams

Hi All,

Don't suppose anyone could explain what happens in an A exam, B exam and C exam and what the frequency of these are?

Just trying to understand a bit more about engineering on the railway

On a Deltic, it was an A every 24 engine hours. And every tenth A would be a B.

As far as I understand, an A exam is really basic stuff like fuelling and making sure the brakes work. A B exam is that plus some more, and so on.

On the Class 165/166 DMU an A Exam is every 7,500 miles, B Exam on 15,000.
Our 387 EMU fleet however don’t have A & B Exams, they have T & M Exams, with T Exams being time based and M Exams being mileage based.

Some BR TOPS exam frequencies for various locomotive classes can be found at the very bottom of this item on the former Cardiff Canton depot:

The requirements differ depending on the type of traction. You also now get examinations such as a 'Balanced B-Exam' where different requirements from higher exams are incorporated into each seperate B-Exam, meaning that the traction unit doesn't need to be out of traffic as long for higher exams.
