Your probably wondering how I got to be CME now.
So am I!
Seriously I don't design diesels as I leave that to the engineering team and I design the steam and rolling stock, so that explains the ignorance.
The reason I write this thread is that we are having some trouble with diesel style test bogies and brakes and so far they are not working very well.
We have seen that when the brakes are left on, the discs will run hot and they are useless.
Is this the same on all diesel locos?
