One place that comes to mind is Winfred M Berg. They have a wide range of small, precision driveline components including gears, plastic chains and sprockets, shafts etc. I haven't looked to see if they have a website.

Other sources you might look at include Portescap coreless/brushless DC motors at:
Plus I've posted another thread about Faulhaber and speed for model loco's as well.

Look at:
GrantLine has some gearing stuff for various locos. It tends to be in plastic tho and thus only for lightweight stuff. Some of the importers have brought in various components for their locos and Precision Scale is probably the best place for that stuff. After that, perusing the swapmeet tables for the odd stuff always helps.

Steve,
Save yourself from Internet translation services and look here :-)

Thanks for your help. John Hudson.
Berg (516-596-1700) is a good source. Also Stock Drive Components (516-328-3300). Both are expensive, compared to NWSL. There's also Boston Gear.
However, the lines if instrument gears they carry often are not suitable for many model railroad purposes without modification (read LATHE). Such gears rarely have the same pitch (mostly 72 dp) and helix angles common on model RR gears. The instrument gears mostly are wider and have large hubs, and are intended for use on larger shafts than we often use in the hobby (bushings may be necessary). Such gears are usually either held to their shafts with cross pins (straight or tapered), or special clamps (like small collets ... we rarely have the space for these). Not to say such components can't be used, especially in the larger scales, but cost and likely modification are issues.
Same goes for their lines of small cogged belts and sprockets. Most are too stiff (steel reinforced belts) for our low power applications. Application would be more suited to the larger scales.
One thing of interest is 'pinion wire'. This is brass or steel rod extruded or cut to a gear shape, with numbers of teeth from about six to
20 or so. You buy it by the foot. You just slice off wafers to make gears. You also need to bore a hole for the shaft. Again, it's lathe work.For model RR purposes, NWSL are hard to beat. They'll even custom cut gears (for a fee of course) for non standard applications and exact replacement.

There are many reasonable costed gears and gearboxes available outside of the US. Try UK, NZ, and AU sites. Doesn't make much sense to buy out of the country unless you buy a bunch as postage can east up any savings. However if you wish to buy $100-$200 worth of materials you might want to research these sources.
