Morphology
A B1 learner who knows 'train' (a procession or railway vehicle) and 'oil' (a slippery liquid) would not be able to infer that this refers to oil from whale blubber; the modern literal meanings of the constituents point toward railway/vehicle oil or a generic oil, so the actual sense is lexicalized and historically derived, not compositional. The term is archaic and etymologically unrelated to the common sense of 'train', making the phrase unpredictable for learners.
Etymology
The noun train oil comes from an old Dutch word traan meaning 'tear' or 'drop' and people used train to name the oily drops taken from whale fat. That's why train oil means the oil from whales that was used for lamps and soap.
