Dinero is my problem. I REALLY like the Atlas ones better, for all the reasons stated above, but it's going to be a Christmas gift for my 15 year old & I want to get him the a & b units. With the costs creeping upwards of over $600, unfortunately I'm probably going to look long & hard @ possibly going with the MTH since they're coming in about roughly $400 for the pair used.

There is no B unit for a GP series engine, just an unpowered unit to go along with a powered unit.

F-3 and F-7, and E-7 & 8's diesels used a B unit at time but not a GP or SD series, just added another powered unit or two.

Here ya go, GP60B

There certainly were B units made in the GP-series.  EMD made cabless "booster" locomotives (hence the term "B" units) for GP7, GP9, GP30, and the GP60M.

 

ATSF had a few GP7 "B" units in addition to the GP60B; UP & PRR owned GP9 "B" units, and UP also owned GP30Bs.  Some of the GP60b units still survive and in service today with BNSF.

 

Lionel offered cabless GP9B unpowered (dummy) units as part of their early Railsounds sets back in the early 1990s, in UP and SP liveries (although the SP never had any "B" GPs in real life).  Atlas O has GP60b locomotives in powered and unpowered versions.

 

So yes, B units for Geeps do exist, in the real world as well as in model railroading.

You sure aren't very well informed about EMD "GP" type "B" units!!!!

He was talking about MTH models, I'm sure, and not the real thing. I presume it was not your experience at EMD that railroads ordered "an unpowered unit to go along with a powered unit" (emphasis added). That is the full context of his "no B units" statement.

Well, since the original poster was questioning whether an ATLAS O "B" for the AT&SF GP60M models, was available, I really don't see any connection to any MTH GP60 models by phillyreading!

What will really get your goat, is that the cabless GP-7's & GP-9's were called calf units. I guess I forgot about the calf units until re-reading the posts on here.

Also not too many companies will do a B unit for a GP unit. MTH might do one.

 

Just off the top of my head I could not think about a B unit for any GP unit. I guess I should have done some research like going to the EMD website and looking up B units.

Down here in Florida, FEC uses multiple lashups of powered GP-40-2's, until they bought some SD-70's.

I don't think you're going to get his goat with that one.

 

 

Some railroad employees that purchased the GP7 & GP9 cabless units may have called them calf units informally (I've never heard anyone call them that myself), but their official classification are as GP7Bs and GP9Bs. 

 

Usually the term calf units specifically pertained to cabless yard switchers, specifically the SW series, and not road switchers like the GP7 & GP9.

Lee,

 

No, the GP9B and other GP "B" units of that early era were NOT referred to as "calf units"! The "calf units" where part of the SW group of switching units sets, for example an SW1200 with acab, and an SW1200 cables "calf unit", both MUed together as a set. The Union Pacific and the C&O even had "Herds", consisting of an SW cab units, and two cables calf units.

 

Besides, the GP class of units had the 2 axle Blomburg "GP" type truck, whereas the switcher class of units had the AAR "ridged" 2-axle "switcher trucks".

 

Suggest you go back and do more research/homework.
