More BEEP info:
My research shows that RMT and Aristocraft entered into a Joint Marketing Agreement in March of 2010, which included sharing a production facility in China. A short time thereafter, the price of the BEEPs jumped from $60 to $100.
The wording on the Box was also changed to say: "BEEP GP 7/9 Diesel Locomotive" on the front.
I think that the BEEPs sold in these boxes, at the higher price, were the upgraded units.
If anybody has a BEEP, with this wording on the original box, it would be great if you would let us know how fast it will run.
Thanks,
