At the National Train Show a few weeks ago, AZL very quietly announced what some would consider a revolutionary freight car in Z...the Gunderson Maxi-Stack I double-stack car. There have been a few requests for more information on this announcement from AZL. So, while I'm not privy to any information from AZL, I can provide some info about the prototype cars and what we might expect from AZL. I'm missing some key research materials located in storage, but I decided to go ahead and get started and fill in the blanks later. The main thing I'm missing is the overall production/series information, but a lot of that can be extrapolated or isn't needed to paint a fairly complete picture of these interesting cars.
The prototype that these cars will (presumably) be based on are 5-unit articulated cars, with 40ft wells designed to carry 20 or 40ft containers in the lower well, with 40ft, 45ft, 48ft, or 53ft* containers in the top position. (*53's do have special loading restrictions) For more on the history, I'll borrow a snippet from Athearn's website:
"Gunderson introduced their Maxi-Stack 5-unit articulated well car in 1988. Evolved from their previous 5-unit Twin-Stack design, the Maxi-Stack (also called Maxi-Stack I or Maxi-I) boasted a lower tare weight (accomplished in part by the elimination of the bulkheads of the Twin-Stack), greater capacity, and greater versatility in regard to container lengths and widths that could be carried.
"Initial production of these cars lasted from May of 1988 through May of 1990 with approximately 270 cars built for Southern Pacific, Chicago Heights Terminal & Transfer, Trailer Train, Maersk, and the Rail-Bridge Corporation. Despite their design advances these cars were quickly overshadowed by newer and even larger designs, and it appeared that the final chapter on the Maxi-Stack design had been written.
"However, due to ever-increasing international container traffic, moving in mostly 20’ and 40’ containers, the railroads took another look at the Maxi-Stack. While the newer car designs with 48’, 53’, or 56’ wells were more than adequate to handle this traffic, the additional car length was unnecessary for hauling these shorter containers with the corresponding excess in train length and increased fuel consumption.
"As a result, BNSF Railway placed orders for new Maxi-Stack cars in 2000. While outwardly identical to the first generation of Maxi-Stacks, these new cars featured minor cosmetic differences compared to their earlier siblings. As of 2007, the Maxi-Stack is still in production, with new cars built to date for BNSF Railway, TTX, Northwest Container, and Arkansas & Oklahoma Railway."
I used the word revolutionary and I do believe these cars will be just that for Z-Scale. These will be the first ready-to-run, Z-Scale, North-American prototype, articulated freight car ever...and that is great news for Intermodal fans. If these cars operate well and are commercially successful, it will almost assuredly pave the way for many other needed pieces of Intermodal equipment in Z. I'll get into more of the technical details about the car and the various road names and so forth, but a couple of points to close this entry:
So, a lot to love about these cars, and it will be an anxious year or two waiting for these to come to fruition. (to be continued...)

- Keep in mind that almost ALL double-stack rail cars ever built are STILL IN SERVICE. There are a few exceptions of course, and factoring cars destroyed in derailments. But given most were built post-1985 they are well within their 40-year service life. (or 50-year extended) So, the Maxi-I's are still making money for the railroads!
- These 40ft articulated cars (along with cars like the Twin-Stacks and LoPac 2000's) are great for model railroads as they portray the look of modern double-stack intermodal trains nicely, yet with a minimum footprint...easier to get a variety of cars for a given train length versus 48ft or 53ft cars.
- The Maxi-I's roots are found in the venerable bulkhead-equipped Twin-Stack cars. Essentially, the difference in the cars is not much more than shaving the bulkheads off, so these Maxi-I cars are also great candidates for a kitbashing project to arrive at the (also still in service) Twin-Stack cars. And who knows, maybe AZL will craftily tool the cars in a way that will yield both models at some point.
So, a lot to love about these cars, and it will be an anxious year or two waiting for these to come to fruition. (to be continued...)
