This is 8x9" straight, 11x9" curved, and 1x9" power curved.  If I've done the math right, that should make a 74" x 38" oval.  I didn't include a transformer to avoid adding cost but have multiple available and will combine shipping.

I bought this used in a big lot and didn't have a use for it.  However, I did test it to be sure it worked.  A few pieces have damaged plastic connectors (connectors that hold track pieces together) but I had no issue getting a train to run the length of the track.

If you have questions, feel free to ask.
