Previous post talked about derailing WBB semi-scale or "baby" Hudson on new Lionel O-27 switches. They won't work smoothly with this engine! So I plan to sell off the tubular track. What's your favorite non-tube track for Willaims engines?

I am new to O gauge and need the advice of someone who knows. My beautiful new Williams by Bachmann Hudson steamer is apparently not made for Lionel O-27 tube track switches. They are obviously made cheaply, and the engine either jumps when it enters the curved route of the switch (it goes okay through the straight-through routing), or completely binds up in the switch and comes to a sudden and frustrating and unacceptable stop! So my question is: Which would be better....work on the switch (which I have no clue how to do), or change to the new Fastrack, which would be 36 inch radius and probably would not stop the engine. My layout space is small.......just a dogbone loop to loop. Are Fastrack manual switches non-derailing? If they are, a loop to loop would have no need to power them.
I'm still like a 5 year old on Christmas morning, and love to just watch a train roll while I work on buildlings and scenery. Any help will be appreciated. This is an awesome place for newbies to get answers.

Just curious. This website offers only an 80 watt transformer under "track and accessories" for Williams trains like the one I just bought. The Hudson engine instructions state it should be run by a transformer of at least 90 watts. What's up? Any recommendations on a good transformer would be appreciated.
Thanks. 

Long time model railroader, but no O scale since 1960! New Williams semi-scale Hudson arrived today, and this is going to sound like I work for WBB, but man! That thing is beatiful. Weighs about 6 pounds, so very solid feel. Wonderful. Just a couple of questions. I never lubricated engines when I was a kid? Is it hard to do? Instructions look fairly easy. What kind of oil should be used? Second and more important question: Can anyone recommend a good transformer for this engine with its four lighted passenger cars on a small one track layout? I have an MRC AC 1301 Throttlepack, but it's rated at only 64 Watts, and WBB recommends at least 90 watts for this engine, so I am afraid of damaging the motor with the weaker transformer. Any power suggestions around $100 or less?
