Stadler officially presented the two new locomotives in Taiwan on 10.7.2023. They are the first ones out of 34 that will be delivered to TRA. These narrow-gauge locomotives (1,067 mm) have six axles and belong to the SALi family product range. The locomotives arrived in Taiwan about a month ago for the acceptance tests on the railway network on the island.
New locomotives were ordered in 2019, and they will have a power output of 2.7 MW, starting tractive effort of up to 430 kN and a maximum speed of 120 km/h. They are specifically designed for Taiwan's tropical and subtropical climate, which can reach a humidity level of up to 100% and extreme temperatures of up to 45º. They will be used in both passenger and freight services, even in multiple traction.
