Here is a small headcannon
When the skr decided to connect to the old msr slate quarry, Duke, Handel, and Sam were ecstatic. Once the line had opened, the slate quarry became the most profitable slate quarry on the island. On the other buffer, the small raggedy blue mountain quarry was running on dimes money wise, and the mine engine and a faceless garatt engine wise. In all honesty, the bmq could make loads with their iconic namesake, "The Blue Mountains", due to te loads of slate in the hills of those peaks, but they were never in range because of their being only one engine who was able to either pull trains to lay rail or/and deliver the heavy slate to the harbours (where they have a contract for slate to
Scotland) so the trains would have to be juggled on a tightrope over lava type schedule. After a year and a half. The bmq had run down to their last $10, and the owner Jefferson Rheneas, was about to close up shop, when the manager of the Skarlowey said that they had a contract for the bmq, due to a spectral incident at the old quarry. The contract, you may ask, is to bring slate from the quarry to a construction site at Crovan's Gate to build a works for reparing, making and upgrading/updating any and all types of steam (fireless included), in return, the Skarlowey would by an engine for the bmq along with their purchase for a narrow guadge works shunter from Cuba. During the constructed of the newly nicknamed "Steamworks", the skr sent daily trains to work on building the quarry up, and during the calmest of days when trains were minimal, the skr would sometimes do construction trains to help build the quarry faster. A week before the new arrivals, "The Blue Mountain Quarry" finally finished the extention construction, and the morning of the arrivals the soon to be officially named "Stamworks" was finished. Unfortunately, during unloading of the new engines an incident occurred where the Cuban engine was accidentally knocked in to a shallow patch of water by the new Irish engine who would go to work at the quarry. Drowning in guilt that he had just killed an engine, the new quarry engine left for work as soon as he was steamed by his crew, who had been allowed to come with their engine. Luckily the yellow Cuban engine was fished out before any majior damage was done, and he got to atend the name christening and become the works very first repair and paint job. Que events of Blue mountain mystery. To this day still, the Steamworks get regular visits and the BMQ is the most profitable quarry on the Skarlowey Railway taking regular slate trains to Ulfstead castle making a tidy profit and getting regular trains of brakeroom snacks in return.
