"* Locomotion was the first locomotive ever to pull a passenger railway train"

depends on the definition of passenger train - Trevithick's 'Catch-me-who-can' pulled a string of wagons containing people but it just went round and round

Interesting to hear it called Locomotion Number One - it suggests that they would either have or be anticipating a Locomotion Number Two - and marks the birth of the train spotter !
