Orr, and his German competitor Hartel , make standard 'HO' scale (16.5 mm gauge) girder rail track. You should understand that if you are not running self contained motive power (i.e. battery w/ RC control) you will have to make many adjustments in terms of insulating and isolating parts of it , if you DO NOT plan to have overhead pickup and multitrack return , as on the real thing.
At one time NJ Custom Brass was Hartl's U.S. importer , and the line was sold by Walthers , but this is not the case today. You will have to contact them directly to find details of how to purchase or go through the WWWs of the big discount foreign prototype sellers (e.g. MICRO MACRO MUNDO , and TEE) to see if anyone is selling them over here.
The large track (and other stuff)manufacturer, TILLIG , produces a system of nongirder rail for street running . I had some questions with this material, but have come around to the opinion that it does'nt look all that bad when installed, and is essentially the only presently extant ready-to-run street trackage that will do the job for conventionally track powered steam railroading. It is a system employing cobbles or brick simulated streets and short portions of tubular rail attached to an insulating underlaying base. It has turnouts, crossovers, dual and single sections of trackage, etc. Tillig , that arguably makes the best looking ready-to-run conventional track ('HO','TT'',and various narrow gauges ) existing, is on the WWW, Many of the importers of European prototypes , as well as some others have it. REYNAUDS, I believe has a photo website of the entire line. In any case ,if you go to : <
http://www.kleinserien.de >
you will have the all gauge German model railroad manufacturers site where you can review everything available by gauge,product type, etc.
Regardless, you should be aware , that anybodys girder rail , and TILLIG's street trackage system will cost at LEAST four times as much per meter as a plain jane TILLIG code 83 Trackage . These are all specially made, low demand , more complicated and labor intensive items to produce.
There are YAHOO groups for: Trams and Trolleys,;for PCCs ;as well as an Interurban group which may be of interest to you. Many of the Australian. British, German, Czech,French, and various other national trolley system modellers have sites on YAHOO's plethora of foreign language groups.
Good-Luck, PJB
