Standard Tankers

Standard tankers are rolling stock used for transporting any type of liquid, rather than a specific type. These tankers feature no logos from other companies.

Personalities
Standard tankers on Sodor fall into the category of Troublesome Trucks, although the ones in African countries are quite the opposite; somewhat silly, polite, helpful and enjoy singing peaceful and uplifting songs.

Types of sentient tankers

Basis
These tankers are based on standard 14-ton pre-war tankers common across most of regions.

Liveries
Standard tankers typically come in black, grey, silver and white liveries. Sentient tankers in African countries are painted purple maroon.
