The GTLW SYS180W-D3T is a heavy haul fast-freight locomotive built by the Gateway Turtle Locomotive Works in 2019. 3 real life examples of this locomotive exist, all being produced between June and October of 2017. The SYS180W-D3T would not be publicly available, and would only be used on GTCOs experimental passenger railway, TurtleTram. The locomotive uses a trio of GTLW HH60I prime movers to generate a total of 18,000 hp (13,420 kW). The locomotive can reach speeds of up to 120 mph (193 km/h), and is designed for fast freight transport. The locomotive's front two AAR type D trucks are located on an articulated front section, which is coupled to the locomotive above the frontmost truck to provide stability and support for the full locomotive. Although the locomotive is very long, its power output makes up for it, as it can carry a good amount of weight at relatively high speeds. The SYS180W-D3T is the most powerful locomotive built by the Gateway Turtle Locomotive Works, and is also one of the most powerful locomotives in the world.
