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.

Watch HSB Steam Engines Battle to the Brocken

The Harzer Schmalspurbahnen (HSB) hauls more than one million passengers a year, and to do so it utilizes its equipment to the fullest potential. The following video shows unmodernized HSB 2-10-2T steam locomotives lugging trains up the 3.3% grade between Schierke and the Brocken in July 2009.

Steam Power - Rolling Along | August, 1945

Fortune ArticleOn this #throwbackthursday, read all about the battle between steam and diesel on U.S. railroads in the 1940's. The cover story of the August 1945 Fortune Magazine addresses experimental advances in steam technology that locomotive manufacturers were pursuing.

While there is some discussion of the ATSF 2900 class towards the end, this article addresses primarily the experiments the Pennsylvania Railroad (PRR) was undertaking in advancing steam. From the T1 to the S2, this article has detail and perspective from the era on advances the steam engineers were pursuing.

RFIRT Rebuild Photos 2 - Disassembly and Sand Blasting

Work continues on the heavy overhaul of the RFIRT locomotives 107 and 119 in Buenos Aires. A decision has been taken this week to complete No. 119 before starting work on 107. This is mainly due to available workshop space which is relatively limited taking into account the storage of locomotive 107 as well as stripping 119 into several component parts. However the two tenders are being worked in parallel. Sand blasting of 119's boiler is taking place this week as well as a full strip down of the rolling chassis and then a full sandblast prior to a thorough inspection. The boiler will be inspected once fully stripped and cleaned. Work has now started on the Sentinel S6 steam waggon and a full strip down is taking place at this point in time.

The following photographs were taken by CSR Director of Engineering, Shaun T. McMahon, on his visit to the rebuilding facility on Tuesday, February 24. Below is an embedded version of the CSR Photostream on Flickr.

CSR announced today that it has been retained to assist the Harzer Schmalspurbahnen, GmbH (HSB), known as the Harz Narrow Gauge Railways in English, to re-engineer the front-end of a 1918-built steam locomotive, including the addition of a moden, "Lempor" exhaust system. The test locomotive, shown above, is an 0-4-4-0T Mallet-type steam engine that is in need of a replacement smokestack. Management at HSB saw the impending replacement as an opportunity to improve operational efficiency and safety.

Images of testing performed on the locomotive and an account of the on-site visit of our Technical Advisor Wolf Fengler, MSME, can be found on our site at
