[Video] Why does it take so long for this Class 50 to start up when cold? (www.youtube.com)

It seems to take nearly 10 minutes to get started. What's actually happening? Are the pistons literally unable to move in the cylinders until the engine is warm enough?

Yeah it was my constant thought when watching it too seeing all that smoke. Fortunately more and more train lines are being electrified.

It looks like this class was withdrawn from service in the 90s (it was built in the 60s) so I can only imagine there's cleaner diesel electrics in service now.
