Trains would leave Sparks with enough engine to manage the 0.43% grade (e.g. a 2-10-2 with a 5500-ton train) and would get helper engines at Wells; the "ruling grade" from Sparks to Ogden could be considered 0.43%. But nowadays the railroad doesn't base helper engines at Wells so trains must leave Sparks with enough power to climb the 1.4% ...

Using a booster engine, though this is usually limited to starting the heavy train; Using two-in-one articulated locomotives such as the Fairlie, Garratt or Mallet locomotive; Replacing the engine with a more powerful heavier engine for the duration of the steep grade; Attaching additional banking engine(s) [2]
[2] [3] The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. [2] [3] [4]
