Reading Company No. 2102 is a T-1 class 4-8-4 completed in the Reading Railroad’s own shops in 1945.
The locomotive’s origin is more complicated than a simple new-build date: Reading created the T-1 class by rebuilding earlier I-10sa 2-8-0 Consolidations using substantial new frames, wheels, and redesigned boiler structures.
No. 2102 therefore combines material lineage from an earlier locomotive with a radically different final wheel arrangement and operating purpose.
The T-1s were intended to handle both freight and passenger work and used 70-inch drivers that balanced road speed with freight capability.
After regular steam service declined, Reading used No. 2102 on its well-known Iron Horse Rambles excursion program.
The locomotive later passed through several owners before returning to Pennsylvania preservation.
Blue Mountain & Reading purchased 2102 in 1986 and used it in excursion service into the early 1990s.
After years out of service, Reading & Northern undertook a major restoration program.
No. 2102 returned to operation in 2022 and has since hauled both passenger excursions and revenue freight trains.
For TransitSatellite, the page must explain that 2102 was not simply built from scratch in 1945. The transformation from an I-10sa Consolidation into a T-1 4-8-4 is one of the most important facts in its engineering history.
