Kato FEF and Kato E9?

Well.......sounds like a good excuse to go DCC

Ah, the (dis)advantages of the low-starting-voltage and high-torque coreless motor! 

Funny you mention this.   Many of the engines I've built or repowered with coreless motors have had
an annoying (    )  habit of "walking" along when a DC throttle is turned all the way down to "zero".
Many DC throttles will leak a little voltage on the outputs unless there is a small load on them,
and apparently 10-15 mA is not enough to pull them down. Add to that the fact that a lot of coreless motors
will start turning with usable power at about 0.7 volts, and there you go.  The engine will just creep along.

I have long since gotten around this by tweaking my home-made throttle so it doesn't leak, and rigging the
speed control pot so that no pulses at all appear on the output when the throttle is turned all the way down.

Another solution would be a center-off reversing switch.  For a commercial throttle swapping switches might be easier.

Yes. All six PMs were going, and working hard uphill into Cheyenne. I was working hard, too - it was a gravel road and I had certainly pegged the "reckless" meter taking this shot while driving.

But it was a priceless moment, for sure. This shot still elicits goosebumps.

Those are actually three PM, UP re-engine them with GP38, 16-645 PM's. The GP38 645 has two stacks.

Thank you for reminding me they weren't two 567's any more. Steve (Lee) said they had to do this to meet EPA regs. This was part of a discussion about trying to find another B unit (his objective), and fast, because any repowering was soon to require a turbo'ed PM. They obviously didn't make it.

No problem, they are basically GP38-2 in E9 bodies since they also did the electronics. I think NS and KCS did the same with there F units but I not sure.

I was wondering how long it would take for someone to notice this!  I knew this was the case but did not have handy source to back it up.
