Hi Dave,
I was lucky to receive an Emerald train as kind of beta tester.
It got motorized with a XL-PF-motor as intended in the building instruction, but
I have used an old 9V battery box (equipped with 6 pc. of 1.2V NiMH rechargable
batteries). This offers 6x1.2V = 7.2V in total and so it will be comparable to
the new Lithium Polymer battery box.
With this equipment the Emerald is slower than 9V trains, but it is obviously
the most powerful train since set 112 (which had just unbelievable pulling
power!).
I am convinced that this drive will be much stronger than the clutching power of
the magnet couplings. So with different gearing you will be able to make up
faster (but less powerful) trains.
If you are interested in the speed of the train, please check out this short
video of my train running at full speed with 7.4V:

With Kind Regards,
Ben

| (...) Ben: Wow. Thanks for the video link! It looks pretty cool running there, and the speed seems to be reasonable. I don't necessarily run my trains very fast, I just usually have 5-7 pieces of rolling stock hooked on back of the freight trains. I (...) (16 years ago, 4-Apr-09, to lugnet.trains)

| Hi Ben, (...) How did you use the old 9V battery box together with the PF motor and IR receiver? Did you create a modified 9V->PF cable? I couldn't find a way to use the old battery boxes with PF using the normal 8886 PF Extension Cable. Regards, (...) (16 years ago, 5-Apr-09, to lugnet.trains, FTX)
