There's a Polar engine a lot like this in an old generating plant in town here, but it just has all the exhausts into a single stack & doesn't sound as good IMHO

That's one heck of an inline 6!  300 rpm is twice as nice as 600.

What a beautiful sound, like a Rolls Royce Merlin in slow motion.

Wow.  This inspired me to upload some videos to youtube.    The Roots of Motive Power steam museum here in Willits

Estep 6 cyl diesel

  it's job, was to replace steam donkeys and haul felled trees into the railway yard for loading onto cars for transport to the sawmill.   

I did not get a video of it starting, it's an air start, and they had a couple tries before they got it going. Took half an hour to recharge the air tank for each attempt.

 also on my youtube, are a couple other machines, steam roller, a geared mining locomotive

 which has it's 2 steam cylinders axial mounted at a 45 degree incline on either side, like a Vee 2 engine.  They drive a longitudinal shaft which geared to the big driver tires.   Steam now has real torque !

It's unbelievable fun being here the days they fire it all up and show off the gear.
