.

Just to share, diesel Belgian locomotives based from F7 and build under license in Belgium during the 50's

They are double cab one and have roll to around 2002

They were the back bones for freight train, upgrade of them were rebuild during the 60/70´s

They used the type GM 16-567C engine 

Here a link forvall GM powered engines in Europe

The Victorian B class was built as a six motor unit, so has more in common with with an SD7 than an E8, which had only four motors.

The original model number was ML-2 (the second type of main line unit built by Clyde) did not suggest that it was an F, E or even SD unit. The traction motor connections were simplified compared to the SD-7 and the maximum tractive effort was limited by this arrangement as can be seen from the diagram listed above.

The locomotive height was limited to 14' 0" and this did not allow enough room above the engine for the radiator ducting used in an F unit. As a result, the radiator fans were located directly above the radiator cores above the engine, two 36" fans on each side. The fans on the centreline were dynamic brake fans, one 36" fan each end with grids underneath, with air drawn in through the side grilles.

As well as a reduced height, the B class were narrower than an F unit, 9'9' over body rather than 10'. The EMD nose pressings had 1-1/2" trimmed off the inner edge before being welded together.  This resulted in the windscreen centre pillar being 3" narrower than the E and F units, which is visible in the photo of the model.

The European built units required a different roof profile, but used the same arrangement of cooling fans. These were called model AA16. Many of these had four motors with a central idler axle, but the Norwegian units had six (unioversal= narrow gauge) traction motors.

As can be seen from the diagram, the rebuilt A class had a 12-645E3B engine replacing the (by then) 16-567BC engine. These rebuilds had a number of problems and only 11 of the 26 were rebuilt, the new remaining engines being used in fifteen new JT22C units fitted with separate HEP generator sets.

has six wheel trucks makes that an e7 of some sort as f7s had four wheel trucks

E units had two engines, not one, so to use your logic it a F7 of some sort

I am probably splitting hairs but the fact that it has six wheel trucks makes that an e7 of some sort as f7s had four wheel trucks. Certainly not an EMD design for either class and probably had a unique designation.

Both engines???

The Bs never had more than one 567, and the rebuilt As didn't need more than one 645.

That noted, the doubled fans do the same thing as on the FMs that used them: substantially as shane noted, greater mass flow of cooling air in a given amount of carbody length.  You will observe that they are notably absent from the considerably-higher-horsepower rebuilds.

I was privileged to be in Australia in 1977 for the 'official' celebration of the 25th anniversary.  I happened to be wearing a GM-EMD 'tie tack' and met Harold Clapp's son on the platform, who was moved almost to tears that someone from EMD in America had come to honor his father's memory.  I did not enlighten him otherwise...

That reminds me of CNJ double ended baby face baldwins.

 

I like the doubled-up fans in the middle. I wonder why they were arranged like that.

 venting of the engine room so to get cool air over both engines and it is easier on the plumbing for the radiators to be a central spot in stead of two separate units.

These guys have made an HO scale model, some of which may still be in stock!

What a nifty looking locomotive!

Replace the VR with VGN and they would look right at home in Roanoke

I’ve located a drawing for the Victorian Railways A class diesels which were rebuilt Victorian Railways B class diesels which were based on the EMD F units.
 
 
While I don't know what was actually changed with the rebuilds, I don’t imagine that the actual dimensions would have significantly changed but have included this site on the B class which has some useful photos...
 
 
...and these guys have made an HO scale model, some of which may still be in stock!
 
 
 
Hope this helps,  
Cheers, the Bear.Smile

Hello All,

What kind of drawings are you looking for specifically?

A double cabbed F unit was produced in Europe.

Märklin/Trix makes one in HO/OO scale. These are 6-axle units rather than the 4-axle North American units.

Perhaps you could find what you are looking for with the European version.

Hope this helps.
