RailSimulator continues to release new content for its train sim RailWorks at breakneck speeds. Earlier this week announcing add-ons The Southern Pacific GS-4 Pack and 0-4-0ST Saddle Tank Locomotive Pack.

Both pieces of DLC bring a variety of new content to the title including new trains, free roams, scenarios and more.

The Southern Pacific pack runs $20 while the Saddle Tank pack currently offers a discounted tag of $9 instead of the standard $13.

From the descriptions:

Southern Pacific ordered a total of 28 Class GS-4 (“GoldenState”) locomotives from Lima Locomotive Works, with streamlined Daylight livery. The GS-4s began to be delivered to the railroad in 1941. Locomotive 4449 was retired in 1957 and was restored to operational condition and repainted into red, white and blue as part of the USA’s bi-centennial celebrations.

The earliest tank locomotives date from the 1840s, one of the first of which was used to build branch lines along the London, Brighton and South Coast Railway in the UK. In spite of the early belief that such locomotives were inherently unsafe, the idea quickly caught on, particularly for industrial use and five manufacturers exhibited designs at an Exhibition in 1851.
