Our Area 51 rolling stock and accessories provide out of this world fun for scale or traditional layouts! These fun new scale rolling stock pieces include a hotbox "cryogenic transport unit", a glowing heavy duty flatcar carrying who-knows-what and another transport unit that the government has left surprisingly open for viewing! The tank car window reveals a large alien in protective fluid within. His partner isn't faring as well in our Area 51 Tank car accident accessory, complete with additional figures and a glowing spill. You can even add more life to your layout with additional new figures available separately.
