I live in Mexico and constantly check Amazon.com.mx for trains. Late at night, a new ad appeared. It was a Lionel remote-controlled John Deere mini-train, at the promotional price of $50 US, with free shipping. Because these ads disappear rapidly, I bought one immediately.
The next day I learned that it does not really contain a remote control. I cannot find out what gauge it is, but if it is HO, its hooked couplings are compatible with several of my HO railcars. Customer reviews rave about its high quality, while complaining angrily that it is not remote-controlled as advertised. And I cannot find it on the Lionel site.
I'll find out on Monday what I bought.
