HO Scale Maxi-IV Side-by-Side Comparison
Kato and Intermountain/A-line Maxi-IV's.
Allowing you to compare the two models on the market as of late 2008, and pick which one you want, in an educated
Gunderson/Greenbrier Maxi-IV: http://www.gbrx.com/PDFtecbulletins/StackCarsMaxiIV.pdf
The Maxi-IV is a 3 unit, articulated intermodal "stack car", with 53' wells. It rolls in a A-C-B set, with 70T trucks (33"
wheels) on the ends, and 125T intermediate trucks (38" wheels).
Major carriers include BNSF & TTX, with others such as NW Container, Pacer, AOK & IAIS also running some.
Kato USA, and Intermountain Railway Company both have released assembled, painted models on the Maxi-IV in late
2008 for the HO scale market.
As of Early November 2008, Kato has released TTX & BNSF cars, IMRC has released BNSF Early & Late, and NW
Container so far, with plans to release Pacer, AOK, IAIS, & TTX in December 2008.

The IMRC car is MUCH better in the detail department. Etched walkways are almost a must in today's
modern RTR market. The IMRC car having scale draft gear will anger just about anyone who is a Kadee only
user, as Kadee does not make a scale width draft gear coupler.
I have no clue what IMRC was thinking when they included 38" wheels all around. One visit to
Greenbrier's website would have indicated that the end trucks are 70T! My IMRC wheels are VERY poorly
turned, causing the cars to rock violently, and make loud clicking noises.
Kato had it right with the wheel sizes, but then included some funky off center bolster, and a press fit Vs.
Kato's intermediate connector LOOKS far superior to the IMRC/A-line version, however only time will
tell if its smaller size will be sufficient for constant use.
Kato's TTX paint is lacking some good quality control, though the IMRC TTX version is still not out, so I
cannot compare their work.
Kato's metal well sides effectively double the weight of the cars when compared to the IMRC/A-line
cars. I cannot get a specific weight for the IMRC cars yet, seems my scale decided to stop working correctly.
