	Locomotives are [[burner devices]] and require [[fuel]] to run; the more powerful the fuel used, the faster the locomotive's acceleration and top speed will be. [[Solid fuel]], [[rocket fuel]] and [[nuclear fuel]] will give +20%, +80% and +150% acceleration respectively, and provide +5%, +15% and +15% for top speed respectively. Multiple locomotives can be used on a single train to increase its speed. If a locomotive has no fuel, it ~~will~~ still be ~~able to move~~, albeit very slowly.
