IPA: /ˈhændkɑːr/
KK: /ˈhændˌkɑr/
A small railroad vehicle that is moved by hand or a small motor, often used for maintenance on tracks.
The workers used a handcar to transport tools along the railway.
Handcar → The word is formed from "hand" (from Old English "hand", meaning the part of the body at the end of the arm used for grasping) and "car" (from Old French "carre", meaning a vehicle or cart). A handcar is a vehicle that is operated by hand, typically used on railway tracks.
Think of using your 'hand' to operate a 'car' — that's why a handcar is a vehicle you push or pull by hand.
