-
C.
standardized steam locomotive design program
A standardized steam locomotive design program is an organized initiative to develop, adopt, and manage a uniform set of locomotive designs to simplify production, maintenance, and operation across a railway system.
-
D.
railway locomotive
A railway locomotive is a powered rail vehicle that provides the motive force to pull or push trains along railway tracks.
-
E.
stationary steam engine
A stationary steam engine is a fixed, non-mobile engine that converts the thermal energy of steam into mechanical work to drive machinery or generate power in a single location.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
