Most train sets are made from wood or plastic. Plastic models commonly use ABS plastic, and some products combine wood and plastic components.

Listings include manual (no-battery) sets and motorized sets. Motorized trains use disposable batteries (examples: AA, AAA, LR44), a listed "2 Non-Universal Lithium Ion" option, or USB-rechargeable batteries.

Many listings state "No Assembly Required." Others use easy snap-together or tool-free assembly; a few require adult assembly with tools not provided. Some sets also need batteries installed before use.

Common extras include small figures and character accessories, party-themed props (guitars, balloons, gifts), stackable number bricks for counting, and costume or fabric pieces for role play.

Most sets include straight and curved tracks in plastic or wood. Common accessories include stations, trees and signs, bridges or crossing gates, multiple rail cars (passenger, dump, fire, communication), magnetic couplers, small role-play props and number bricks, plus items such as a remote or a water bottle for smoke effects on motorized sets.
