Morphology

train + of + thought

The noun 'train' can be understood as a procession or series, and 'of thought' specifies the domain (ideas), so the meaning 'a series of connected ideas' is directly compositional from the constituents. This metaphorical use of 'train' to mean 'sequence' follows a common English pattern (a X of Y = a sequence of Y) and would be inferable by a B1 learner who knows the parts.

Etymology

The noun train of thought imagines thoughts as carriages on a train, each linked so one idea leads to the next. If the train stops or is interrupted, the link is broken, so the phrase means 'a series of connected ideas' or 'the flow of thinking'.
