I have several of these on hand. I decided to work on converting them to DCC and doing what I can to make them look a little better. The biggest defect in appearance that can easily be corrected is the numberboards, which are clear plastic and stick out at an unrealistic angle. I decided if I could paint these and add numbers, it would make an overall difference in how the model looks. I also had some Microscale 87-793 F unit data decal sets on hand, which would give me decals to add step kick plates and the numberboard numbers. The step kick plates would also be subtle improvements.
Here is a 1975-run Soo Line unit I found at a good price on eBay with DCC installed not long ago with kick plates and numberboard numbers added. i had previously also painted the grills silver and touched up the skirts and steps with black:
For comparison, here's how it looked when I got it: This will be an ongoing project, with the next steps being a winterization hatch and weathering. These lasted into the 1980s on the Soo and were pretty beat up by that time.I found a 1990-run Soo Line body on eBay pretty cheaply and installed it on a chassis I had on hand. Again, I added kick plates and numberboard numbers.
This will also get a winterization hatch when the lockdown ends and i can go out for glue and paint. The 1990 run locos had their grills already painted silver.Here is a 1990 run CP loco that I added a Juneco CP style winterization hatch to when I got it. I added the kick plates and numberboard numbers. The loco has been pretty beat up over the 30 years I've had it, and it will get weathering.
With all these locos, I think small changes in paint and detail distract attention from their less-good vintage features. I really like the way they run.
