車掌
しゃしょう · shashou · JLPT N2 · noun
conductor
🚃 車 (car/vehicle) + 掌 (palm/hold): the one who holds the train's controls and tickets
車掌 literally means 'vehicle + palm,' like someone who keeps hold of the train. The sound 'sha-sho' is easy to repeat when you say 'the shah of the shop' to remember the pronunciation.
