[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?

“That exhaust will clear right up” I’d be surprised if it did, even when they were newish Class 50s could produce an impressive plume of exhaust smoke. When I was a kid spotting on the Western Region main line and these were in regular service we learned not to stand directly above them on the footbridge at the station 😀 They make a great noise going at full chat though.
