Hi friends, For those who want to digitize AZL's Rail Diesel Car I found an interesting solution. Actually there's no dedicated decoder for this vehicle except Digitrax and TCS solutions (still with some soldering work), but they don't offer extra functions like sound or interior lighting. By the way, I wonder why AZL do not cares about interior lighting in their passenger rolling stock like many other manufacturers in other scales - it would be great to have at least possibility of installing such upgrade kits (remember Rokuhan products). Not so long ago Rokuhan announced A059 universal DCC interior lighting board that not only switch headlights and taillights, but can also work as a locomotive decoder too. It's quite unique solution due to its features and size. In addition, it is quite cheap. PCB can be reduced to many different sizes by cutting various number of segments. The smallest size fits in small German rail bus (Marklin 8831) and old passenger cars with the same size. After cutting one segment A059 decoder perfectly fits in AZL RDC. Easy wiring and very little soldering work allow to convert RDC to DCC very quickly. 5 remaining LEDs after cutting PCB are enough for smooth interior lighting. After wiring decoder can be easily attached to the shell with 1 mm thick double-sided foamed adhesive tape. No need to continue the story, just look at the pictures. Regards, Alex

This is a good question! The answer is simple: money. Our cost to include a passenger car with lighting is about 50% more than without. To prepare the tooling to accept an upgrade kit for the possibility of adding lighting at a later time increases the cost by about 30%. We decided that these expenses - just making the models ready for lighting kits - would not be used by enough of our customers to justify a 30% increase in price for everyone. We also find that there are other options - like battery powered interior lights - that do not require any modification to the trucks, or reduced performance due to additional rolling resistance of the electrical pick-ups for the lights. On the other hand, I really like the way you have improved the RDC! Cheers, -Rob(A) AZL

You know I've been playing with the A009 lighting board for use in the heavyweight and SuperlinerĀ® cars, but never thought about the RDC, I'll have to try it this winter. I've read that some people complain about the motor being visible, but I figure that's what window shades are for. We also find that there are other options - like battery powered interior lights - that do not require any modification to the trucks, or reduced performance due to additional rolling resistance of the electrical pick-ups for the lights. I put a fair amount of time investigating possibilities. A AAAA battery or button batteries will fit and give about 4 hours of reasonable operation. Replacing them is the pits unless you were to redesign the chassis to take them. Rechargeable cells work with about half the lifetime. Battery lifetime can be extended by using pulse power. For recharging the batteries, there are pickup coils that will fit inside the cars so you recharge them like an electric toothbrush, they double the weight. But can you imagine a charging track for your AutotrainĀ® or trying to plug in 20 charging cords? My best solution so far is a conductive tiebar (2-sded PCB) and draw power from the locomotive. The challenge here is getting the entire train on the track. There are some micro-miniature coax connectors, but they would more than double the cost of a car. Maybe this will spawn some new ideas.

Mark, motor is not visible in RDC. The floor level is high enough to hide it almost completely. I think that idea of window shading is to hide PCB that is located exactly in the center of car at the window level and clearly visible. Digitizing of RDC with A059 allow to remove stock PCB completely, however some wire added instead of it.
As for battery powered interior lighting: some may disagree with me, but I think that this is a totally weird idea with a lot of obvious disadvantages. First, the fact itself that something on layout is powered by battery, while everything else by external constant power supply is absolutely irrational, as for me. Any kind of battery power source (AAAA, button) that will last for at least an hour will need a lot of space inside any passenger car and it ruins the basic idea of lighting. And keeping in mind the fact that light will dim with time as the battery will drain is a nightmare I think. I don't even talk about ability of switching on and off the lighting and recharging or replacing the batteries.
So the only reasonable way of adding interior lighting (for those who really need it) is modifying of trucks and installing analog or digital lightboards. RDC is very convenient for this purpose because it already has a power inside.
