What is another word for train oil?
Pronunciation: [tɹˈe͡ɪn ˈɔ͡ɪl] (IPA) 
Train oil is a type of oil that is derived from animal fat, specifically from the blubber of whales and seals. The use of train oil has declined since the 19th century due to a shortage of whale populations and the advent of petroleum-based oils. However, there are still a few synonyms for this oil, including whale oil, blubber oil, marine oil, and sea oil. Whale oil was historically used for lighting, lubrication, and as a fuel source. It was also used in the production of soap, cosmetics, and margarine. While the use of train oil has decreased, it is still important to understand its place in history and the development of modern resources.
