For a number of years, Walthers has dominated the MLRR with its vast variety of passenger car equipment.  In addition to being the primary manufacturer of all of the MLRR's Amtrak equipment, it has provided the MLRR with commuter train equipment as well, including Metro-North, New Jersey Transit and METRA. 

Not only has Walthers established a foothold with passenger cars but quickly became the primary freight car provider as well.  The MLRR's obsession with Autoracks lead to an acquisition of over 10 autoracks in addition to a number of well cars, coal cars and other freight equipment.  One is hard pressed to point out a piece of rolling stock on the MLRR that isn't produced by Walthers.

Although the MLRR now owns a few freight cars produced by Bachmann in their standard line, the manufacturer is most noted by the MLRR for the production of the Acela Express.  Bachmann is the only manufacturer of the North American high speed train set and thus has established itself as a primary manufacturer represented on the MLRR



Rapido is a canadian-based model railroad manufacture that is relatively new to the industry.  Despite its small size and operation, it has provided some serious competition to more established model railroad companies.  It has also raised the bar for quality, detail and accuracy of model railroad products.  Thanks to Rapido, it has had its collateral benefits to model railroad consumers across the board..  As a relatively new contributor to MLRR equipment, Rapido's first product to be acquired by the MLRR was a canadian-based phase III Amtrak baggage car back in 2008.  Seven years later, Rapido burst onto the scene with the production of a number American prototype locomotives, most notably the FL9 in Amtrak and Metro-North paint.  Rapido has been regarded as one of the most highly praised manufacturers when it comes to accuracy and detail.  For years the MLRR envyed other model railroads that Rapido products of the time were catering to and the railroad wondered when it would benefit from high quality Rapido models.  As of 2015, Rapido released the most accurate version of the F40PH locomotive.  While the MLRR has no use for these locomotives in its current operations due to the retirement of the prototype, it still would like to invest in the Rapido F40 for nostalgia purposes.  For this reason the railroad though it prudent to wait for the Rapido to produce versions with ditch lights as this would be more consistent with the MLRR's practice of keeping up with modern prototypes.

True Line Trains is a Canadian-based model railroad manfuacture.  True Line Trains is responsible for bring the MP36/40 to the HO model railroad market between 2013 and 2014.  The MLRR currently owns seven (7) MP36 locomotives for its MARC, METRA and VRE commuter services.  While the manufacturer is responsible for making a variety of model railroad products including its own line of paints, the MLRR has not acquired much else in the way of True Line Trains products.

Atlas Model Railroad Company Incorporated has probably made the biggest splash in the MLRR's history than any other manufacturer represented on the MLRR.  In 1999, Atlas announced the production of the Amtrak AEM7 electric locomotive.  This was the first time this model would be offered in plastic.  This took MLRR operations to another level.  For the first time since the Bachmann E60CP's pancake motor failed, the MLRR could operate trains found on the Northeast Corridor.  Atlas had filled the missing link as the MLRR could now operate true Metroliner trains, Sliver Service trains and all other Amtrak trains operating out of Penn Station other than the Lake Shore Limited and/or Empire service.  The railroad owns over 10 AEM7s, a number of which are in the process of being re-built into AEM7ACs.  For 9 years, the railroad has continually purchased AEM7s and it wasn't until 2008 that the MLRR broadened its selection of Atlas products to a Dash 8-32BW.  Atlas provided the MLRR with its first sound-equipped locomotive in the 8-32BW.  Atlas has been regarded by the MLRR as well as many other modelers as having the finest running quality. 

The first locomotive owned by the MLRR was a Bachmann E60CP which was acquired in Denver, CO in 1994.  Given its poor performance, Bachmann had fallen out of favor with the railroad until the MLRR was exposed to the Spectrum Line.  In 1999 Bachmann announced the Acela Express in its Spectrum Line.  Although it would be another 3 years before the MLRR would acquire the Acela Express, the railroad was completely satisfied with its running capabilities.  Bachmann had redeemed itself with the MLRR and re-established itself as a regular go-to manufacturer of motive power.  Bachmann further solidified itself with the release of the HHP-8 locomotive which performed even smoother than the Acela Express.  The quality had come a long way from the pancake motor of the E60CP.  Since the success of the Acela Express and HHP-8, the Railroad purchased 5 of the first 6 Freight locomotives from Bachmann in 3 different road names. 

Athearn first burst onto the scene with the introduction of the ubiquitous Amtrak, AMD-103 or P40/P42 locomotive.  It's superior running ability compared to the pancake motored E60CP from Bachmann and F40PH from Life Like made Athearn a contender for MLRR motive power funds.  The majority of locomotives on the MLRR consist of P42 locomotives and the MLRR has recently added a number of Athearn freight locomotives to the roster.  The MLRR is also a proud owner of some Athearn locomotives with factory equipped decoders and sound which were produced in their Genesis line.

Broadway Limited Imports is the latest addition to the MLRR in terms of manufacturers represented on the MLRR.  The 2010 release of the AC6000 in the modern CSX paint scheme attracted the MLRR.  The railroad has seen other products demonstrated and was impressed but until the railroad was able to branch out of passenger-only operations, unless BLI produced modern Amtrak motive power or rollingstock, it was unlikely that the MLRR would ever experience the fine quality of BLI.  Fortunately that changed in 2008 and in 2010, two years after expanding into freight operations, the MLRR acquired its first BLI locomotive.  Although pricey with DCC and sound, it is likely that the MLRR will look to BLI in the future for any other motive power it has interest in.
