There is one small problem, I have been trying to find this companys models all year, and it is truly a "Deadlocked Trench situation" for my part as the company that produces this and other WWI models has been out-of-business since 2006 or 2008.
However, Try the links posted on the review, They may have some old stock left, as Austro-Hungary and WWI trains in general do not recieve much attention.
Also, 5-Star produces two Railguns. Here is the French railgun review: http://www.landships.freeservers.com/fivestar_305mm_m06_rrgun_kitreview.htm
It goes without saying but it is a MOST COMPLICATED KIT to assemble.
Here is a review for the German railgun: http://www.landships.freeservers.com/new_pages/5star_kurze-bruno_kit.htm
This Kit needs to be backdated from a WW2 to the WWI version.
Finally for a good starting point, especially for troop trains, Reviresco produces a good engine, with alittle time, effort, and research, you could rework it into an armored model. to find them just go to: http://www.tin-soldier.com/cgi-bin/ustorekeeper.pl look under TRAIN in the catgories.
Hope this all helps.
Regards, Josh

Matador Models make a WW1 flatcar. W^D Models do various railway waggons. Meridian Models make (I think) two different Simplex's.
And I have seen some of the toy trains from the Thomas The Tank Engine range turned into armoured locos in use in Africa. However, I can't find the link at the moment.
