Cat on the Hill - Caterpillar Powered CPRS 4711

[@MikeG42]

I love the sound of those CP Alco/MLW units. Thanks excellent video 😊👍

[@tprdfh51]

I ran 4711 when she was in the Toronto Terminals area in the early 1990's...a special bulletin had to be issued regarding her use of anti freeze as coolant - when an engine shut down in sub-zero weather the procedure was to drain it before the water in the cooling system froze; not necessary with this unit and on a few occasions engineers would drain the cooling system not realizing it was very expensive anti-freeze they were draining! :-O

I noticed the cat doesn’t sound significantly different from its alco counterpart or did you notice a difference when operating it?

[@tprdfh51]

@@skyraiderjet It sounded quite different when operating it...mainly because it ran at twice the rpm of an ALCO.

[@skyraiderjet]

tprdfh51 The ALCO must be louder then the Cat because I hear more chugging then anything else. How did it perform compare to other locomotives? I’ve hear some say that the throttle response is different on the cat that they preferred either EMD or ALCO.

@@skyraiderjet it was quieter than an ALCO...didn't notice any difference in performance compared with other units other than it didn't overheat like the ALCO's did!

Thank you for sharing your comments here about the MLW M636CAT, now (in storage) on the Minnesota Commercial Railroad, as #71.

CP 4711 , then MCCR 71 was bought by Chemin de Fer Sartigan up in Quebec to be used on future expansion on their rail coverage in 2024.

I miss the 4711 rode in her many times!

Great video, looks like they were really working to make it up the hill

[@TonyFleetwood]

this is such a great video!

[@MBAJunction]

I miss seeing those blue C40-8Ws on a stack train, and hearing their Leslie 3-chimes. I NEVER thought I'd be making that statement 20 years ago...

What year was this filmed?
