The steam locomotives "ATLAS" and "VESTA" were passenger locomotives of the KFNB . They were from the locomotive factory Jones, Turner & Evans 1839 / 1840 delivered and had the axle formula  1A1. Since they corresponded to the English 1A1 design, it can be assumed that they had cylinders located under the smoke chamber and a cranked drive axle.

It can no longer be said with certainty whether the locomotives had the same dimensions when they were delivered, but a few years later (see table) they had different dimensions. In 1841 there were complaints about underperformance. That is probably why modifications were made.

The machines were retired in 1861 .
