Well it's been quite awhile since I've posted any new installs. It's not that I haven't been doing any, it's just that the types of installs I've been doing I had already covered. But here's something new, how about a Japanese train.
I took a look at the decoder offered by Kato for their Japanese prototype trains but could not see how that would work with this model. That decoder seems to be designed to use with some of the later releases that have a hatch on the bottom to install the decoder. I settled on the TCS Z2 for this installation.
A - There was room within the roof under the raised part but the wires would be very visible inside the windows.
B - There is a large pocket in the frame here but I was afraid of the decoder rubbing on the drive shaft.
C - I took the conservative approach and chose to just place the decoder inside near one of the ends.
The front and a rear ends to this car need to be established so that when we later add decoders to the end cars so the lights will be coordinated with the motion of the motor car. To do this I referred to the instruction sheet that comes with the set. These sheets are in Japanese but I have found the drawing shown below to be very helpful. The cars of this train are numbered 1 to 6 with the motor being in car number 3. These types of trains are bi-directional and when they reach the end of their run, the operator walks to the control cab at the other end so there really is no front or back. For DCC purposes I like to think of car 1 as being the front. The writing and arrows under the end cars refer to a destination.
The orange and gray motor wires are cut at 2-1/2 inches. These motors are identical to the ones in Kato's American prototype locomotives except there are no flywheels. The brush assemblies are removed from the motor and these wires soldered to the brush caps. Then the brush assemblies are re-installed in the motor. The white magnet on the motor faces down.
OK, so that takes care of the motor car. This train and ones similar to it also have end cars with both head and tail lights in each one. that will be covered in a future post.
