As of 2025, the locomotive is owned by the Railroaders Memorial Museum (RMM) in Altoona, Pennsylvania where is it has been undergoing operational restoration.

1361 was originally equipped with a square oil headlight, a round number plate, a long wooden pilot, and a 70-P-75 type tender, which held 7,000 US gallons (26,000 L) of water and 12.5 tonnes (28,000 lb) of coal.

1361 was re-equipped with an electric headlight, a steel bar pilot, and a keystone shaped number plate.

1361 was re-equipped with a cast steel pilot and a vertically retractable coupler along with its headlight and dynamo's positions switched from the front and top of the smokebox.

1361 swapped out its original 110-P-75 tender with a 130-P-75 type, which held 13,475 US gallons (51,010 L) of water and 22 tonnes (49,000 lb) of coal.

1361 sat on display outside exposed to the elements, so the members of the Horseshoe Curve Chapter of the National Railway Historical Society (NRHS) were volunteered to repaint and maintain the locomotive.

1361 from its display site and moved it to the Railroaders Memorial Museum (RMM) in Altoona for its fifth anniversary.

[19][20] On April 12, 1987, the locomotive moved under its own power for the first time in 31 years and made its first excursion run from Altoona to Bellefonte, Pennsylvania.

[5] It also ran excursion trains on the Nittany and Bald Eagle Railroad and Northern Central Railway.

1361 pulled an excursion on the Conrail mainline from Altoona to York, Pennsylvania, but during the return run, the locomotive suffered a main bearing and drive axle catastrophic failure near Lewistown.

1361's boiler shell passed an ultrasound test, but the backhead was discovered to have needed additional repairs, so the whole locomotive was disassembled inside Conrail's Altoona Car Shop.

1361 locomotive was moved to the Steamtown National Historic Site in Scranton, Pennsylvania, for its rebuild to begin.

[25] But the restoration work progressed slowly, since to some its original parts needed to be replaced with fabricated duplicates.

1361 at the Steamtown facilities were cancelled, since the RMM stopped paying out the funds and made the decision to return the remains of the locomotive and its parts back to their property.

[21] In February 2019, the group has planned to design a new boiler in order to meet the current Federal Railroad Administration (FRA) and mechanical engineering standards.

[33] On June 24, 2021, the museum announced that they hired the contracting firm FMW Solutions to rebuild No.

[13] At the same time, the Pennsylvania Railroad Technical and Historical Society (PRRTHS) donated $100,512.33 to the RRM for the construction.

[38][39][a] By December 2022, the new firebox was nearing completion, although with thicker steel and other modifications of the 1914 design in order to comply with current FRA safety requirements.

[40] On February 13, 2023, the RMM acquired an ex-PRR B60b baggage car from the Railway Excursion Management Company for use behind the proposed No.

[45] The original PRR firebox design significantly increased the cost and complexity of the work.
