Careful. Those MRCs are prone to producing high voltage spikes. How are you measuring 2VDC? A meter? It won't detect the spikes; you'd need a scope for that.

Yeah I just ran it for a few seconds with the MRC. And I'm using a small meter (now that I have one that works!) Only thing close to a scope I have is a pair of binoculars 
I usually use the Zthek for T, but I'm not at all impressed with it, even in other scales. The Zthek came with a 9V power supply, but I use a 5V one. I bought a 3V supply and it didn't work at all with the controller. |

One of my end cars has a very dull headlight. At full speed it can barely be seen. The tail lights are very bright though. So a faulty LED is another possibility. My trains have only been run from the Eishindo controllers, so over-voltage is most unlikely.
I haven't pulled that particular car apart yet. I guess it's possible the LED is full brightness, but not correctly aligned or some other reason.

Hello,
in search of a replacement for my destroyed tgauge LED I found the following distributor:
http://darisusgmbh.de//shop/product_info.php?info=p16754_HPT0603WWR
HPT0603WWR - Bicolor Led warm white red 1,000 EUR = One EUR
incl. 19 % Tax excl. Shipping costs
Product No.: HPT0603WWR
warmwhite-red in one case
Parameters:
common anode
white x=0.447 / y=0.416 156 mcd U = 3,1V
red 626nm 44 mcd U = 1.9V
Imax= 20mA, recommanded is 8mA
(because of the common lens with phosphorus seems the colour
red more dark)
Please note the very small dimensions,
(difficult to solder wire on it)

These are seriously cool LEDs. The only problem is that they emit both colors of light from the same SMD, whereas the T Gauge cars have separate LEDs so that they illuminate different lamps on the ends of the cars.
The vendor also has 0402 warm white LEDs, which are the first I've seen, and these have endless potential, especially for things such as streetlights and other illumination challenges.
I just ordered a bunch of the bi-colors as well as the 0402 warm whites, lots of reds (think crossing flashers and signals), greens and yellows, red-green bi-colors (again, signals) and blues.

Thanks, tgauge-friends,for your very friendly offers.
I will send you a personal note.
Regarding my PWM-controller pls. find this information:
It is an extension of the mini-club FUN-Start-Set 81520.
The designer of this part is a Z -friend named Jeremy Brandon.
The distributor is manfred joerger ( www.system-joerger.de ).
Jeremy designed several versions.
I am using the above mentioned controller very often because of its simplicity, 9V battery, moveable.
The deluxe version is more comfortable and I use it for my fixed layouts.
You can get both by manfred joerger.
More infos you can find here:

Yes, the Joerger is a popular throttle for Z scale. Similar to the Zthek.

Thanks for the information. I also found this while searching ebay:
http://www3.sympatico.ca/kstapleton3/851.HTM
Only $40.
If my throttle doesn't end up working I will probably buy one of these. |

oops.
For some reason I thought the one you linked was the Cool Crawler thingie. (expensive)
I'd hate to buy it and find it's no better than the Zthek, but they do show a trim pot so it may be possible to find the sweet spot with this throttle. Plus I notice is runs on AC just like Armand's. |

OK, so I just received my order from DARISUS (http://darisusgmbh.de//shop/product_info.php?info=p16754_HPT0603WWR). I ordered 0402 SMD LEDs in various colors for any number of future projects--T scale grade crossing flashers, for instance.
Well, up to now the smallest LEDs I had were 0603s, which are tough enough to work with. But 0402s... Good grief, they are impossibly small! I'm seriously thinking about buying a cheap, low-power microscope just to work with these things!
Here is a strip of 0402s compared to a ballpoint pen tip...

WOW! Those are small David! It looks like they are as small as the point of that ball point pen!  That is so cool, but there is no way anyone can solder something that small without whatever special equipment they use in factories.

Well, as it turns out, it wasn't as hard as I'd expected. Using #40 solenoid wire, I added pigtails to a red 0402, and it looks like this:

Holy macaroni! That's insanely small.
Is it even worth to detail a layout with flashing lights? Most of the time they are too bright anyway and take over the whole feeling of the layout, mostly in a negative manner.

IMO, it most definitely is; lights can bring an otherwise ordinary layout to life. However, LEDs that are driven to full brightness can overpower subtle effects. Also, some folks cram as many blinking things into a scene as they can (which often flash at an unrealistically fast rate), which can make it look like a circus. The best approach is to adjust the brightness of each lamp or device until it seems realistic, and to keep blinking things to a minimum and, for things that do flash, set it at a realistic pace.
Here's a twilight scene from my last (N scale) layout. I made an effort to illuminate everything that would be in real life, including auto headlights, brakelights and blinkers, intersection stoplights, pedestrian crossing lights, crossing flashers and of course streetlights and building interiors.
