Five years after the Tela bought the long-winded 44 (Locobase 15060), the railway returned to Eddystone for a smaller Consolidation. Still an oil-burner, this engine weighed less and had a smaller boiler served by a proportionately larger firebox.

Baldwin's building pace had slowed considerably in the year after Eddystone produced the Tela's #40 (Locobase 15427); fewer than 450 builder's numbers had been assigned in the twelve months between the 40 and 41. The new Consolidation was based on the 40 but had a bigger boiler and wider firebox, but the latter was to ride above the wheels, which decreased firebox heating surface area. All the Tela's Baldwin Consolidations were oil-burners, but the 41 weighed the most of the three.

Locobase notes with interest that this locomotive's "length of haul" was expected to be 120 miles (193 km), a long distance for so small an engine. Traveling on 50 lb/yard (25 kg/metre) rail on sleepers laid 24" (610 mm) apart, the 44 faced ruling grades of 1.25% and curves of 17 degrees (radii of 338 feet/103 metres).
Together with the Truxillo, the Tela marked a significant step for United Fruit in that it was an entrance into the Honduran growing areas. The railroad led from the northern Caribbean port of Tela (actually a contraction of Triunfo de la Cruz in common use by 1829). Begun after gaining a large land holding from the Honduran government in 1913, the Tela's railroad mileage amounted to 93.2 (150 km) by 1915.
