So, I just received my 2nd locomotive (from my wife) as a birthday present. She got me the Williams SD45 (Santa Fe). I have to say, I was quite impressed. This locomotive only cost $119 brand new (plus $10 shipping), is scale in dimensions, has dual can motors with flywheels, metal gears etc....
So I opened it up right after work, lubed it up, threw it on the track in front of my 20 car consist and she fired right up. Keep in mind that 12 of the 20 cars are full-scale and very heavy cars with the other 8 being 3 dome tanker cars. My track is about 60 foot or so around and is all o72 curves. When I got it up to 15 - 16 volts, it completely derailed the entire 20 car consist and itself flew right off the track !!! Luckily, there was no damage to any of the stock or the engine.
What's crazy is that I run my Lionel SD60e Legacy engine with the exact same consist all the time at full speed and it's never even come close to derailing itself or the consist. I actually believe that this engine was going twice the speed of my brand-new Lionel SD60e.
So, I haven't had the chance to dissect my Williams SD45 yet (but will this weekend ) and have some questions for the experts here on the forum:
1) Are these Williams motors larger/more powerful than what the Lionel's are using in their diesels - why is thing so dam fast?
2) Are Williams engines known for being "strong" pullers generally speaking of course? Can they outpull their Lionel and MTH counterparts? This engine is lighter than my Lionel but pulled the 20 cars like it was only 3 or 4. Having said that, my Lionel also pulls this consist with no problems but nowhere near as fast.
3) Other than lubing the gears and axles, is there any other lubrication needed inside the locomotive? Mine didn't come with an instruction manual so I'm not sure.
4) I've seen some random posts here and there where people say they wire their Williams Locos in series to "slow" them down a bit and help with the slower speeds. How do you do this and does it affect top-end performance? Will it cripple pulling power?
5) Also, when I run this thing at 13 Volts, it's pulling around 1.5 amps (with no cars behind). My Lionel Legacy (set at 19V of course) only pulls around .6 to 1.0 amps and that's with smoke, lights, bell horn etc... Is this because of bigger motors????? Why such a difference in amperage draw?
I must say, I'm highly impressed with this engine. It is only conventional but does all the basic stuff that I need it to. And for $119, man you can't beat that. It is not as flashy as my Lionel, but it still looks and runs very nicely. It's not quite as quiet as my Lionel but still runs very smoothly. Has decent details as well.
