RFIRT Rebuild Photos 5 - Machining, Assembly and Refurbishment

CSR Director of Engineering Shaun McMahon forwarded along these images of work progressing on the rebuild of two Rio Turbio 2-10-2 locomotives in Buenos Aires. He is serving as a quality assurance engineer on the rebuild, and the overall pace and quality of the rebuild is quite impressive! Enjoy on this #FIRTfriday!

HSB Update - a Primer on the Master Mechanics' Front End

On this #techtuesday, learn all about the Master Mechanics' Front End and how CSR is implementing one on a 1918-built 0-4-4-0T on Germany's Harz Narrow Gauge Railways. Read all about it in CSR's RESEARCH AREAS section.

This image shows Harz Narrow Gauge Railways 2-10-2T number 99 7241 as it battles the 3.3% grade between Schierke and the Brocken. Locomotive 7241 was built in the mid-1950's in East Germany and is one of 17 on the HNGR (currently 12 are in service). Known as the "new build" locomotives, these sizable engines are the standard power in the Harz.

John Philip Sousa: 3 | Steam Trains: 0

Perhaps no musician gets played more on the Fourth of July than John Philip Sousa. He was a prolific composer and band leader, traveling the world in the time of passenger trains and steam ships (the band traveled more than a million miles by train!).

Little known is the fact that Sousa and his band were involved in no fewer than three train accidents throughout their career. This image shows band members standing in front of their train, which had experienced a head on collision on the The Northern Pacific Railway in 1899 as they headed from Portland to Spokane. Sousa's band also endured two other derailments in the 1920's, one near Rochester, New York and one near Walsenberg, Colorado.

See Tracks? Think Train!

Wishing all a happy, and safe, Fourth of July!

New CSR White Paper

CSR released today a new White Paper that outlines the thermo-mechanical behaviors associated with steam locomotive fireboxes (including the firebox sheets, tube sheets, tubes and staybolts). This technical paper was originally written by modern steam engineer Livio Dante Porta in 1984 / 1985 during his work on the ACE 3000 modern steam project in the U.S. As such, the White Paper also includes information specific to tests undertaken with C&O steam locomotive 614 and issues it had with staybolt leakage.

This White Paper has been digitzed by CSR from the original hand drawn and hand written piece, with slight editing for clarity. Be sure to read it, and all of the other CSR papers, on the CSR White Paper Program page.

CSR Launches

CSR announced today the launching of a new website dedicated to the past, present and future of ATSF steam locomotive number 3463. This site,, features many never-before-published images of the 3460 class, extensive detail on the history of the locomotives, and a clear outline of plans to return the locomotive to steam.

CSR will still continue to use its main site,, for the majority of information, while this new site will serve as a semi-static "repository" of information. It is a one stop location for information on the 3463. Be sure to check it out and learn about the impressive class of locomotive.

RFIRT Rebuild Photos 3 - Cleaning and Machining

Hard work continues at Cromwell Marine on behalf of G&G Metalmatica on RFIRT 2-10-2 steam locomotive 119 in Buenos Aires, Argentina. CSR Director of Engineering Shaun McMahon is serving as a quality assurance engineer on the rebuild, and he took the following photographs March 17 as part of his inspections.
