Between 1928 and 1934, almost all of the C-5 class locomotives, with the exception of No. 25, were sent to the LSI's Presque Isle locomotive shops to be extensively rebuilt and modified to improve their performance. Their boilers received superheaters and were raised higher above the frame; their fireboxes were widened and received [[Thermic siphon|Nicholson thermic siphons]]; their cylinder saddles were replaced by ones with superheated cylinders and piston valves; and [[feedwater heater]]s were installed. The upgrades added to the C-5s boosted their tractive effort to around {{convert|42,000|lbf|kN|0|abbr=out|adj=off}}, and the rebuilt locomotives were reclassified as SC-4s.

No. 18 was the third C-5 class 2-8-0 to be built, and it was originally numbered 11. The LS&I initially assigned No. 11 to pull mixed freight trains and occasional iron ore trains alongside the other C-5 locomotives.{{Harvp|Durocher|1958|p=14}} In its early years, due to its poor steaming capabilities, No. 11 was prone to stalling when the weight of its train exceeded its pulling power, or while the locomotive was climbing a grade. When the LS&I merged with the MM&SE in 1924, No. 11 was renumbered to No. 18.{{efn|The No. 18 was previously assigned by the LS&I to [[Western Maryland Scenic Railroad 734|an SC-1 class 2-8-0]], which was subsequently renumbered to 34.{{Harvp|Schauer|2015|p=30}}}} In 1930, No. 18 was rebuilt and modified as an SC-4 at the LS&I's Presque Isle shops, and its capabilities were radically improved.
