West Lake Transport Authority (Chinese: 西湖交通管理局), often referred to as West Lake Transport(西湖交通) or WLT, is a state-owned enterprise founded by BDark focusing on transport and property development (e.g. TOD) in the West Lake Area of Let's Play server.

WLT was founded on 8 August 2022 after its first plan, Chung Kwo Kok and Wong Yip Island Development Plan, has announced. It was originally planned to call Western Railway Company (Chinese: 西部鐵路公司) with West Rail or WR (Chinese: 西鐵) as its abbreviation. But since the WR abbreviation is used by Wilds Railway, the name was changed before the formal establishment.
