These
are Omnicon
urethane BF16 “Sharks”. I did not assemble them, I bought them painted from
eBay. They were a kit offered in the early 1990s with NWSL drive components
as Omnicon’s only urethane offering. Omnicon was a S Scale only brass importer mostly of steam locos in the
late 80s and early 90s. The
decal job could have been a bit better. I pretty much painted over all of the
areas that were not decaled, added an all wheel pickup electrical system,
made the drive bulletproof, added DCC and lights, and lots of stick on tire
weights! They have really good pulling power now. They compliment the River
Raisin/Boo Rim http://riverraisinmodels.com PRR A-B-A set I got. I also got a
River Raisin B&O A-B set. I went from 0 to 10 Sharks in March 2006! I am
now cut back to 7 total as I sold an unfinished
Omnicon A B A set. |

2006 Photos
These
are some photos for 2006 when I first got them. 2 photos are from running on my
friend Bill Moore’s layout that is now dismantled. I also have a photo display
track I took a lot of model photos with my first digital camera.
This
is how I did the DCC installation in 2006. I have mostly backed off of the all
wheel pickup since getting decoders with capacitor banks like Keep Alive or
Current Keeper. Modern electronics makes the loco run well if there is a small
power interruption. These are actually Alco sideframes – good enough.
June 2020
I
had not run these for a while. They were always a bit stiff on the initial start
up but otherwise ran well. This was a very early DCC installation for me. They
needed an update to a modern decoder and LEDs. Maybe I should have put sound
decoders in but I did not at least for now. For a diesel set like this I will always
run them together so I program all decoders as the same address even if it was
4 units. I never do consisting. They run a lot better now with the new decoder
and a fresh lube job. There is still a bit of gear noise. I found out what happens to 14 year old LaBelle grease. Not good!
This
is the 2020 version of the drive. I removed the flywheel. The decoder does a
much better job of supplying momentum. Flywheels are never truly balanced
anyway. It is a NCE D13NHJ decoder. I added a short driveshaft to the motor
coupling on the A unit. You can’t get the motor and gearbox perfectly aligned.
I am sure that was an improvement. Note all the tire weights!
I
generally do not install cab lights but I did for this loco. I remembered I had
to make a CAB, so I figured I would light it.
