Dan’s been back in touch again with his HO switching layout plans:
“This installment of the Santa Fe layout has the switchers (shunters) at work. The layout has to earn its keep.
Photo 1 The grain elevator has its own loco.
Photo 2 New farm equipment arriving.
Photo 3 Picking up a TOFC load. (Trailer on flat car)
Photo 4 Moving machinery to the trans load facility. This is one of my very lightly weathered locos on my switching layout. I can do it. I just prefer not to do much weathering.
Photo 5 It looks as there will be ham at a market soon. Also notice the trainman at the call box. He will be asking for permission for track and time to the yard.
Photo 6 Moving a HO caboose.
Photo 7 Loads on the way to a farm show. I used the date of the show to set the time period of the layout.
HO switching layout plans:
Photo 8 Tale of two HO switchers. Both are Athaern locos. 2685 was 56 years old in 2015 when the other loco was purchased. The older loco was a kit. You had to build up the gear drive. The loco is still in service and is a little noisy.
Photo 9 Switching in the industrial area of the layout.
Photo 10 Scrap loads. I did removable scrap loads for a friend. His cars were “colorful” to say the least. His layout was featured in the post about the scenery on the helix.
Photo 11 A road HO switcher on a work train doing repair work. (Road switchers had higher horse power, different trucks and geared for higher speed.)
Photo 12 A special move. The load is on one flat car and an idler car on either side to allow space for the load to be moved.
Photo 13 A close up look. I use #8 button thread to lash down the load. The thread goes through the stake pockets on the flat car and kept in place with super glue.
That is all for now. I have a few night scenes to post next before I move on to other layouts I have done. If Al lets me 8+)

A huge big thank you to Dan for sharing his HO switching layout plans and pics. And yes, please do keep ’em coming Dan.
That’s all for today folks.
Please do just mail me if you have anything you’d like to share.
Richard has been in touch with a wonderful ‘how to’ on battery powered model trains:
“The documentation of the Extended Helix Railroad indicated that I had advanced to a battery powered railroad.
The main document provided electrical schematics of the battery interface, but no pictures.
I have located the pictures and will provide them in this appendix.
While working on the Extended Helix Railroad, I added a small linear test track and a small Christmas Tree Railroad to check out the battery operation.
The linear test track was approximately 2 feet long and had a power supply connection which allowed non‐battery trains to be tested.
The power supply interface also provided a connection for an oscilloscope for monitoring the digital pulse width performance of the engine when running on a power supply or on battery supply.
Figure 1 shows the linear test track was used to monitor the pulse width modulation and Figure 2 shows the loop around test track that could also serve as a Christmas Tree Railroad for the Holidays.
The tree stood in the center and the grandkids got their fix of model railroading.

Some of your astute readers may notice that the houses under construction on the upper level are sized for HO unlike the buildings on the lower level that are correctly sized for N Gauge. The HO Gauge versions were not available in N Gauge at the time of purchase just before Christmas.
Thankfully the grandkids didn’t recognize the size differences between the upper and lower levels.
This test track could be operated with a power supply for trains not equipped with a Control Chip and Battery Supply, or with a Control Chip and Battery Supply for the trains already converted to battery operation.
Figure A3 shows some of the construction techniques used to add battery power to the trains.
The picture shows four flat cars with a “B” size Lithium‐Ion battery in each flat car.
The “B” designation is not an official size designation. It is my documentation of a size that is bigger than my “AAA” and “AA” size Lithium‐Ion Batteries but smaller than my “C” and “D” size Nickel Metal Hydride Batteries.
The “N” gauge engines are too small to add the chip for control, a speaker for sound and the Batteries to achieve approximately 15V power.
The Pennsylvania Railroad Engine would appear to be large enough to support the chip and a speaker, but I found that the dimensions of the engine were just a little too small.
I decided to install the control chip and a speaker in the box car closest to the tender and install two “AA” size Lithium‐Ion Batteries in the next two box cars. This configuration permitted the three box cars to be joined with different engines if I re‐initialized the chip before running the next train.
The engine must be identified with a specific engine label to calibrate the chip for a new label and appropriate engine short circuit current draw for safety.
I interconnected the engine and cars via gold plated military grade pins and number #30 heavy “foam‐var” insulated solid copper wire. The pins consist of male and female connections that can be easily separated but still provide a low loss junction.

Battery powered model trains:
The “B” red colored Lithium‐Ion Batteries on the four flat cars shown in Figure A3 offered much longer train operating time between charge times. These 3.7V batteries were heavy and required at least four flat cars to achieve the 15V power for the train.
The train composition was an engine, tender, one box car (the controller and speaker), and four flat cars each containing one “B” Litium‐Ion Battery. Any remaining freight cars would be added at the end of the train.
The battery laden flat cars were always placed forward of all freight cars to prevent pulling over the freight cars on tight curves when the heavy battery flat cars were placed after the freight cars and to prevent running the power wires to the engine any farther than necessary.
The batteries provided three to four hours of running time and never exhibited the potential fire condition reported by the news media during operation or charging due to a safety circuit built internally into the battery casing.
The second generation of battery powered model trains was developed using “AAA” Lithium‐Ion Batteries that were installed on flat cars or within box cars. I was able to install four “AAA” LI Batteries on each flat car shown in Figure A4 or two in each box car as shown in Figure A3.
The train could be operated for nominally two hours with one flat car or two box cars.
The third box car containing the control chip and speaker was required for the single flat car or the two box cars. This shortened the train for better use of additional freight cars.
The battery connections on the flat cars needed to be taped to prevent snagging debris along the track and in the tunnels. The battery connections in the box cars have socket pins installed in the box car roof to interconnect the batteries and the control car with the engine as shown in Figure A3.
Packaging of four “AAA” lithium?ion batteries on one flat car
An example of the Ring Engineering Control Chip LM3S is shown in Figure A5.
Four LM3S Control Chips were installed in four different box cars to operate four different trains.
Three additional LM3S Control Chips were installed in an Amtrak Baggage car Figure A6, and two dummy F3 Diesel “B” engines Figure A7 to accommodate the three operational passenger trains.
Two additional Amtrak baggage cars were set up as battery cars as shown in Figure A8.
Since the track power will no longer be used, all lighted passenger cars and cabooses needed batteries to energize Light Emitting Diodes LED with a current limiting resistor and a means to turn the lighting on and off.
These cars were powered by a 3032 Series Disk Battery in each car. Each car was configured with three roof mounted socket pins to turn the LED on and off and a connection to charge the individual 3032 battery from a remote charging source. A metal staple was connected across two of the exposed pins to complete the electrical path and then removed when the LED was to be turned off.
Figure A9 shows the electrical installation of two LEDs, a 3032 Series Disk Battery and Figure A10 shows the roof socket pin connections.
For example, charging is made by inserting two pin connections in the wide spaced sockets in the Pennsylvania Railroad PRR passenger car from a charging power supply.
One of the charging sockets and a close spaced socket are interconnected by a metal staple when passenger car lighting is desired.

A huge big thank you to Richard for sharing his ‘how to’ on Battery powered model trains. Clever stuff.
Boyd’s been back in touch with more of his stunning HO scale scenery:
“Hello Al,
I’m attaching a few pictures of the progress made over the winter.
As usual, I did not get as much accomplished as planned, partially because of other projects that seem to pop up and demand my time, and partially because my trial-and-error approach quite often veers in the direction of error.
In any event, it’s always a learning experience, and all great fun.
A couple of the pics may be repeats of earlier submissions, but I made a few changes, and started with a pic of the quarry area and worked down the mountain from there.
For those who did not see the earlier posts, this is HO scale, benchwork is roughly 12×15 feet, and operated with NCE DCC system.
There will eventually be an area dedicated to each of the grandkids, you will 3 of them in this group of pics.
One grandson presented me with a picture of me and him working on a scene, it proudly hangs in the train room.
Here is the scene he worked on, you can see where his interests lie..

Well, that’s it for now, Summer activities and travel will limit my time to do much more until the late Fall. Take care, and thanks for your support for the hobby.
