The "most variations" game...

[jbaakko]

So I just brought up an interesting idea, lets see which wins out. Which Locomotive series has the MOST variations!? I brought up the EMD 70 series, and EMD 40 series. We're only talking original builds, not rebuilt units (I.E. the SD40 rebuilds, of BB40-2's)

70 Series:
SD70M, SD70I, SD70M Tier I, SD70M Tier 1 Phase II cab equipped, SD75M, SD75I, SD70MAC, SD70ACe, SD70M-2.

40 Series:
SD40, SDP40, SD40X, SD40A, SD40-2 early, SD40-2 mid, SD40-2 late, SD40-2 Canadian (straight steps), SD40-2 high nose, SD40-2 snoot 108", SD40-2 snoot 116" SD40-2 snoot 123", SD40T-2, SD40T-2 snoot 116", SDF40-2, SD40-2F, SD40-2W and SD40-2S (SD40-2SS/SD40SS).

So far it looks like the 40 series wins, anyone?

Glad I finally talked you over to the 40 side. :P

[CP9302]

The SD40 series by a long shot. CP has at least 10 versions of the SD40-2 alone!

[jbaakko]

Yuppers, I've settled on the 40 series, though those 70's are catching up!

[CP9302]

BTW Josh, you missed the standard SD70 that IC, NS and CR got.

[jbaakko]

Oh wow, I KNEW I was forgetting something!

I think the SD60's are third SD60 SD60M (three window) SD60M (two window) and conrails SD60I (isolated cab) and isn't the SD75M a different class and if not you can add the SD45 and variations to the 40's list.

[jbaakko]

EMD classed the SD75's in with the SD70's.

There is also the SD60MAC that BNSF (BN) has.

[jbaakko]

Huh, I somehow passed up the SD70MAC Tier I...

Is it a requirement that the manufacturer had a separate designation for the model? If not I think Baldwin might win for either the AS-16 or AS-616. They never got over the steam locomotive mentality of custom building locomotives (In my opinion the lack of a mass production mind set is why they went out of business.). So while they were all called AS-616s, there were as many variations as there were customers. This is also why I have such a hard time identifying Baldwin locomotives even between manufacturer models. Other than a few things like the knotches in the frame for the AS-616 for the brake cylinders, they are almost as hard to tell apart as a GP7 from a GP9.

No, not at all, describe away!
