Here are some photos of the latest great looking tank car from Atlas. The Marvelube is the lastest custom run by the Canadian Toy Train Association club car. http://www.canadiantoytrains.org/
(New updated Website coming very soon)
And some shots of the car with other previous limited releases by the club. Click on photos for a larger view. The BA oil car is nice as well. The PGE trailer on flat from Weaver they also did one with a BA trailer on flat.
Some hobby shops have this and the older cars in stock.
