The Unofficial Micro-Trains Release Report (UMTRR) is the oldest and most read INDEPENDENT monthly review of and commentary on Micro-Trains Releases in N, Nn3 and Z Scales. The website contains archive editions and back issues of past columns plus release tables, special features on Micro-Trains and exclusive web-only Micro-Trains content.

Here you'll find links to listings of Micro-Trains releases, special features and back issues (archive edited versions through 2009, PDFs after that).

I encourage you to subscribe to the full-length UMTRR via e-mail... just click on the link to find out how! Subscriptions to the UMTRR are free... really! And worth at least that much...

UMTRR Back Issues, in case you've missed one.
The UMTRR Wish List, for those who'd like to help with, or help find, specific items for the UMTRR Research Accumulation.
"Micro-Projects" and "Micro-Stories"
Items that will (hopefully) be of interest to Micro-Trains enthusiasts and modelers, available only here on the website!
The States of the Union Series
Micro-Trains regular run and N Scale Collector Only cars plus a cross-reference table!
CAUTION: Many images will load with this page.
Canadian Provinces and Territories
The Micro-Trains Special Edition Series honoring the our neighbor to the north. Also includes a cross-reference table.
CAUTION: Many images will load with this page.
A Holiday Gathering
A rundown of the Micro-Trains N Scale Holiday Cars produced from 1991 onward. Includes optional large images (must have pop-up enabled).
CAUTION: Many images will load with this page.
Runner Packs #1 & #2 (April 2007)
Micro-Trains' initial "Runner Pack" offering, including a "family portrait" of other releases of this Pennsylvania Railroad boxcar. Now with images of Pack #2 (Santa Fe boxcars).
Box Car Loads - "Uncovered"
A look at the first few Micro-Trains boxcar interior loads, with and without the boxcars that carry them.
"Car One"
The first Micro-Trains car!
Based on the original numbering system, anyway...
"If You Knew Susie"
The evolution of the Micro-Trains Susquehanna Box Car.
"Conrailized"
The "repaint" of a Micro-Trains Penn Central Box Car.
"Door Thing"
Putting a prototypical eight foot door on several Micro-Trains 40 Foot Box Cars.
"@BW?!?"
An attempt to explain exactly what this Micro-Trains variation means... fortunately, with illustrations direct from the UMTRR Accumulation.
Fun With Multimarks
How to be thoroughly confused by the placement of the CP Rail's symbol on different sides of the Micro-Trains 24260 boxcar. Truly trivial? You be the judge!

And... the UMTRR FAQ (Frequently Asked Questions)
(I didn't know where else to put it)
