Matt,
There are (NiMH) 10Ah 'D' cells out there.
Also (NiMH) 5Ah 'C' cells.
I have both. I got mine from 'batteryspace.com'.
A 10Ah battery car will last you all day. I use it as a back-up to my onboard batteries (4.4Ah sub'C' cells) on my GP7.
I have only 12 volts onboard the engine which I like when switching (mostly indoors). Once I have a train assembled and want to take her outside on the open road for a while - then I'll cut in the battery car (14.4V) and use that as my power source. It gives a little more top speed (maybe a scale 45-50mph) than the 12 volts will.
My engine has provisions for both power sources.
And as stated above.....remove the smoke unit and replace the incandesent bulbs with LEDs
