I can distinguish C30-7s from U33Cs and U36Cs. I can't find the difference between U33Cs and U36Cs. Is there even an external difference?
There may be some minor ones in different phases of production, but the biggest difference is inside, unseen, with the engine. 3300hp to a 3600hp engine. By all practical reasons however, a U33C could be made a U36C as they are 99% identical.
Phase for phase, they are identical... just different fuel rack settings (similar to a C40-9W/C44-9W) Unlike U33Cs though, wheelslip control was mandatory (i.e, not an option) on U36Cs.
Yes! U36CGs had no walkways, and were semi-streamlined, with ribbed sides to match the passenger cars they pulled. IIRC, Santa Fe was the only owner.U34CHs, IIRC, have a HEP setup right behind the cab. Only Erie LAckawanna got 'em for use on NJ Transit commuter trains.
U34CHs are easily recognized from U36Cs, they lack the intake filters on the carbody. Sante Fe had U30CGs... not U36CGs. NdeM was the only owner of U36CGs, these were not streamlined. They were basically U36Cs with steam generators... Note the doors on the forward compartment as well as the vent up top...
The early U33C had an external feature you could easily spot. There was a fairing from the hood, to the radiator housing. Boxcab E50
Spotting feature for what? We're talking about the differences between a U33C and a U36C, not a U30C and a U33C... Phase for phase, U33Cs and U36Cs are identical... the first U36Cs were uprated SP U33Cs (they also have that fairing)
The original question Triplex posed ended: "......... I can't find the difference between U33Cs and U36Cs. Is there even an external difference?" The fairing I noted, IS an external spotting feature, that definitely visually sets off some U33C from U36C. I actually saw these back in the late 1960's. Boxcab E50
You're talking about a Ph IIa vs a Ph IIb... Look at it this way... How do you know you're looking at a U33C if it has the fairing? Conversely, how do you know you're looking at a U36C if it doesn't have the fairing? You don't, regardless of phase... that's my point.
As per his original question, which presumes you are looking at either a 33 or 36, then you know it's a 33. Boxcab E50
How do you know it's not a U36C? Don't say becuase it doesn't have the fairing either... Eventually, you'll figure out what I'm saying... rather than repeat myself ad-nauseum, re-read my previous posts.
Boxcab, Robbman is saying that the U36C had the same fairing in it's same phase. IE, they are exactly 100% the same. Each time there was a phase change to one, there was a phase change to the other. Therefore, the fairing is not indicative of one or the other. Now then, could somebody post a link to something that backs up their position? I for one am curious and listening to two schmos argue without supporting evidence isn't so much fun.
Ah, word play. You'll have to forgive my senility. I'm trying to recall events from before you guys were born. :teeth: I don't recall seeing a 36C with that sheet metal. Some of the earlier ones ordered were Milw 8500-8503 (later 5800-5803.) I remember seeing them new. They did not have that fairing. Boxcab E50
