+Mike Troina When I got my first camcorder in the early 1990s I tried to get footage of as many locomotive models in action as possible and now I am digitizing and publishing some of that footage but it is a slow and time consuming process.
Awesome video. We miss them so much. Do you know anyone who could have caught CN SD40 5011 before its crash on Yale Subdivision in 1969? I know that 2 years isn't that much for a railfan to see it even once, but in case, I'm trying to find a picture of it. Thanks David!
+Jam Tuazon When diesels were first introduced 4 axles was the norm hence the term General Purpose. Occasionally extra pulling power was needed - for example starting very heavy trains or on steep grades and so 6 axles were used hence the term Special Duty. The disadvantage of 6 axles (12 wheels) is there is less of the locomotives weight on each wheel as compared with a four axle loco (8 wheels). Hence it is easier for slipping to occur. With increased locomotive weight this is no longer a problem and six axles are often necessary for the load limits not to be exceeded - this could result in damage to track and structures such as bridges.

4:39 I really like this shot through downtown halifax for some reason. Unfortunately the second track you see beside the engines has been ripped up.
4:40 must have been one of Bubble’s shopping carts on the track. It was Halifax, after all.
He forgot one
Ah the SD 40 DIESEL! I have this scale model in Athearn Ho Blue Box series great shots of them in action. 😃
can’t believe any railroad would option out of DB….just crazy (btw i’m a railroad engineer)
Too expensive then
nice video David and great catch of all the different cn power on all the different train's.

OK that's cool.

Sorry I don't. Why don't you inquire on yahoogroups "CNlines - CN Sig"
Cheers
Ahh. Cool. Lange Züge fahren kann ich noch nicht
Nice snowy scenes, for a change, cool!
+Wally Plue Yes we do have winter!
Is the video with the 2100 and 2122, old enough to be HR616's? Or are they really C40-8's? It was nice to see some M-420's too. Great video as always!
+NewBoston Truck 2100 & 2112 are HR616s. I did a full video on the HR616s see th-cam.com/video/C0d_EnHGHds/w-d-xo.html
Great old video!
i think the term in locos "SD" means Special Duty like SD40, SD70ACE, SD90MAC-H SD50, SD60, SD9, SD7, SD40-2W, SD40-2LW and so on
+Jam Tuazon That is correct. GP is General Purpose!
but one thing i'm trying to hold on to, why are the special duty locos 6 axles and the general purpose locos 4 axles?

ok thanks
+Jam Tuazon You are very welcome.
