The Aerotrain is an automated people mover system located within the Kuala Lumpur International Airport in Malaysia.

A 75 kW (101 hp) DC electric motor (model number: 1460-P4, controlled by a thyristor drive) constitutes the propulsion system of the trains.

On 28 December 2021, a local engineering firm, Pestech International Bhd has secured the Kuala Lumpur International Airport (KLIA) Aerotrain project for RM742.95 million, which involves the upgrade of the 1 km (0.62 mi) automated people mover system at the airport, together with the Aerotrain's operations and maintenance, for a 10-year period from 2025 to 2034.

The new rolling stock was delivered in September 2024, and transport minister Anthony Loke stated the system was planned to reopen by the end of January 2025.
