You are right a lot went for export, I think Brazil took quite a few, but BN were still using them in the late 90s if photographers have put the correct dates on their photos. I really should fit some ditch lights to mine, even if they won't work.

I got a picture of C30-7 BN5537 in a consist at Mendota on 12-10-96

Thanks Brian
Pictures of the back end of them seem to be rare.

Guess in the end of 1996 they must have been on their last legs for a class 1?

Hi Brian
Certainly they were on the way out. They were bought to haul coal trains in the late 70's and early 80s BN and Santa Fe were the biggest buyers in the US .
BN used those mainly for hauling coal out of the powder river basin.
I've found photos of them dated as late as 1999 still hauling coal trains. The worked on most other things bar the container trains too.
I've also found photos dated up to 2016 of them operating on shortlines still in their BN green livery.

I've been doing a bit more on the green machine, first decals, what a difference they make.
The micro scale decal sheet I was using didn't have any number board numbers, it was just the big numbers, but I managed to find some on SD60 sheet that I bought on the off chance that they might be useful one day as they were half price in the P&D sale.
Last night I added the MU hoses, Kadee couplers and windshields
It's starting to look the part now.

I've now been spending a bit more time on the SP SD9s. About 150 of them were rebuilt during the 70s and became referred to as SD9Es.
Visually there were two obvious changes, some (about 20 from what I can find) were fitted with a Farr Air Filter Box, most had a rain shield behind the cab that extended the cab roof profile back a fair bit. This was to help prevent water ingress into the electrical cabinet. Others also had light changes made with the gyra lights and emergency red lights removed on some locos. So the plan is to draw the necessary parts and print them. The first one I have tried is the Farr Air Filter Box. I couldn't find a drawing or any information about them, just a few photos of locos with them.
So this is what I think it needs to be.
It's too long across the body, by about 1.5mm, but I'll fix that on the next print.
Next I need to do the rain shield.

Unfortunately Stephen, that glass was from last night, I just hadn't got round to washing it up.
I am about to open another bottle shortly but it is heading for 6pm

It's been bugging me since this conversation, that I was sure I had seen locos 'similar' to the C30-7 somewhere......memory finally kicked into gear - Cuba!
Not my photo, but I'm sure I did take some photos of them in and around the Havana area.....in fact I think I had passenger haulage behind one on an overnight train from Havana to Santiago de Cuba, will have to dig my photos out. There was definitely a loco swap about 30min outside Havana where the original train loco died a death - I'm sure I took a photo of the replacement loco on the buffers at Santiago....
According to Wiki, the Cuban fleet of C30-7s was purchased from the Mexican national railroad, about a similar time as they started importing other second hand GMD1's from Canada...
Cheers,
Stephen

Over the weekend I had the urge to do some machining.
These are massive freight cars, over 18 inches long, but they run on tiny wheels, I think they are 28 inches on the real thing.
For once Atlas have actaully used the right size.
They look tiny compared to 36 inch wheels. So to convert these to P48 it's a case of reprofiling and thinning the Atlas wheels.
These are the smallest wheels I have had to deal with but all the usual techniques work, the one exception being that the form tool needed grinding down a bit or it would have removed all the support from the back of the wheel.
You need to pull the trucks apart to get the wheels out, including removing the springs from one side so be careful not to lose them.
You will then need an arbour press to remove the wheels from axles as the axles are knurled and they just won't pull off.
Here are the finished wheels, 1.3 mm thinner with a nice P48 flange. The easily go back on the extended axles on the roller bearing caps keep the side play down.
I forgot to take photos of the finished autorack, so that will have to wait until next week once I'm back from Chicago.

Seeing one of these in the flesh....it is a truly massive piece of kit; HO ones are big but these O gauge ones are enormous and impressive.
