On a recent visit up to Canada, Brian had the opportunity to revisit a few home layouts. Excellent layouts included Justin’s, Walter’s and new this year, John Johnston’s. Justin Parry’s layout is featured above; John Johnson’s is featured below. These layouts all illustrate the craftsmanship and hard work that goes into building a quality model railroad.

Brian, in conjunction with Mark Bean and David King, has been steadily persevering at the software program to operate the reverse loop for the N scale T-trak one trak project. It seems that the simplest things are not as simple as they might at first appear. The overall concept of the reverse loop is to have a train enter going in one
direction and exit going in the opposite direction. Automating this means that the software has to recognize where the train is at any given time, what the power requirements are at that time, and changing any necessary hardware to
accommodate the train as it moves along. All this is pretty straightforward, but implementing it with the software and getting it to operate the way it is planned is nowhere near as simple as it sounds.

First, the hardware does not always cooperate. Checking the polarity is not always reliable, so the software needs to
be written to compensate for possible misreadings. Then the magnetic sensors have to be checked and again compensated for any misreadings. Finally, all the action has to be timed perfectly, and put together in one complete package designed to operate without failure. Sounds easy enough but in reality, it is much more difficult and mostly, time
consuming than it at first would appear. Persistence is the order of the day and Mark, David, and Brian will keep at it
until finished. A photo of the temporary setup is pictured below.

Brian and Greg spent a productive Saturday putting together the new modules. Greg had already done most of the preliminary work by trimming the framing wood to the correct size. All that remained was to miter the corners, build some supporting blocks, glue, nail, and assemble the pieces. Final construction included putting the tops on the frames and trimming with the router. A few hours later, and the modules were ready for painting and track work. Greg took his new treasures along with him to work on them more at home. We anxiously await the presentation of these new modules for public viewing.

FUNTRAK member Greg Brockway is finding out that it can be lonely at the top. Greg has been diligently constructing HO scale T-trak modules for display at FUNTRAK functions with very little help. He did manage to get some assistance recently at Brian’s when they worked together to construct two specialty one-trak style modules and one more double to incorporate into future layouts. Greg has been and continues to be the mainstay for thre HO division of FUNTRAK. Please note Greg, your efforts have not gone unnoticed. Keep up the great work!

FUNTRAK members Lorenzo Franchi and Jim Domser contemplate the new one-trak modules under construction. These new modules will add variety and some different concepts to the ever expanding t-trak modular system. This will allow for linear layouts and make the inevitable circle unnecessary if so desired. Of course, the one-trak tee will also allow the one-trak concept to be tied into the regular t-trak layout making all kinds of new innovative designs possible.

Innovation! What a great idea. Unfortunately, as Edison said, “Genius is one percent inspiration and ninety nine percent perspiration.” So I am ambitiously pursuing my brilliant idea of how to do a simple job with the least complicated solution. Developing a means of having a train go down a single track, traverse a reverse loop, and return to its origin with minimal human intervention. Seems simple enough, doesn’t it? Whoa! Let me tell you what I have done so far and what I foresee as yet to come in this “simple” endeavor.

First, I had to overcome the skepticism of my fellow helpers who all claim this is way too complicated to be done simply and efficiently. To do this I sent a preliminary drawing out and asked for help. This at least convinced them that I was serious, even if they thought I was still crazy. Now that the communication exchange had begun, the ideas and answers began to pop up. Some of the simple things that needed to be solved included how to automatically change the polarity of the tracks in the loop without having to stop the train, how to notify the engineer when the main throttle direction should be changed, how to protect the mainline from having the train go against itself when coming out of the loop, and the list goes on. Control of these functions is dependent upon knowing the location of the train at any given time. Here we go again!

Now I have to find some way of sensing the position of the train and relaying it to some sort of control mechanism. I decided that an Arduino microcontroller should do the job of providing a control mechanism for all the operations necessary to control the power supply for the trains in this section. I also decided to see if Hall effect sensors would work as the means of providing the necessary position indicators to feed this information to the Arduino. Again, simple ideas but complicated answers. How many Gauss does an electric train motor radiate? What, you say. So did I. I need to know something about these little motors in order to use the Hall sensors as a sensing mechanism.

How many relays does it take to control the polarity of the power being fed to the track? Simple suddenly doesn’t seem so simple any more. To answer these questions, I ordered the parts I would need to complete my experiment and test my brilliant ideas. Now all I have to do is wait for them to arrive.

Meanwhile, I am trying to figure out the magnetic pattern of my little locomotives so I know how to position the Hall sensors in the track, if in fact they will work at all, to detect the little trains. If, and that is a BIG if, this all works out as planned, I then need to delve into programming the Arduino to control the necessary hardware to accomplish my end desire. As you can see, what Edison was alluding to is that as each solution for a simple problem comes up, so does another problem required to be solved to support the original idea. Nothing is as simple as it at first appears.

I will keep plugging away at my problem and eventually either come up with a satisfactory solution or realize that it “simply” cannot be done.
Until next time, keep training.

Here we are in November, National Model Railroad Month, and the schedule of events is extremely busy. Following a torrid building month in October, FUNTRAK members are now preparing to attend some of the larger shows with the new modules ready for display. First up is Syracuse where FUNTRAK will debut the new mountain module section of the N scale t-trak division. Club members worked diligently throughout October getting these modules ready to be displayed to the world. Three work sessions and numerous nights were devoted to making everything operate properly. John Fleming then worked his magic on the scenery to ensure the modules would be at least presentable for the shows. Hopefully, all goes well at Syracuse with FUNTRAK and the other participants. The planned layout will be over five scale miles around and should present an interesting layout. The main line is set to operate with DCC while the remaining loops will use conventional DC power. This arrangement will allow everyone to have a chance to see how mixed power can be applied to a layout and operated successfully.

Following Syracuse comes Fulton the very next weekend. FUNTRAK is scheduled to bring both N scale and HO scale t-trak layouts to this show. Again, work sessions in October enabled the club to construct six new HO modules, four standard and two doubles. Greg Brockway, FUNTRAK’s resident HO guru, has been charged with getting track put down and fellow club members have committed to helping him in the scenery department. The only glitch may come in the area of space that is allocated for the layout in Fulton. FUNTRAK will fill whatever space is provided.

With Christmas right around the corner, the annual show at Oneida County Historical Society is currently in the works. Clayt Farrall is doing his usual coordinating with the administrators to confirm dates, show times, space available, and details for the show. Anticipated dates this year are Wednesday, December 26 for setting up and running through Saturday, December 29. More information will be announced as it becomes available. Pictures of some of the new modules expected to be in the previously mentioned shows are on the next page. A well deserved “Thanks for a Great Job” goes out to all the club members who donated their time and effort to making these new modules possible. It is wonderful to have such enthusiastic individuals to associate with for such a great common cause. Next year will bring new challenges, different opportunities, and even more fun for our club as we move on to our twenty first year. Come on out and support your club!

Lots to be done to get FUNTRAK modules ready for the November shows in Syracuse and Fulton.

FUNTRAK continues to expand the size of the club layouts displayed for the public. Again this year the t-trak layout got larger and the new HO t-trak layout was included at the Fonda Fair, thanks to one of FUNTRAK’s newest members, Greg Brockway. The week-long train display draws many visitors and fascinates observers as they watch multiple trains traverse the many routes available on the numerous different scale layouts on display. The hard work of the members of the clubs involved pays off in the many smiles from the public to the people presenting the great model railroads at the fair.
