Main Line has Begun Work

Work crews finally began construction of the main line! 

After months of planning, changing, analyzing, and more planning, the main line work has begun.  I have gotten the first straight away and about half of the big curve laid down, both roadbed and track. 

The above picture show the main on the right and the yard on the left, with only the straight part of the main line. 

The turnouts are Atlas #6, one for the passing siding (left hand) and one to go to future industries.  All mainline and industrial track will be code 83, mostly all Atlas product.  I used code 100 in the yard for reliability purposes.  Depending on this layouts success, I will most likely use code 83 for all future setups.

Here you can see the beginning of the curve.

Now you may be wondering "why is he making such a big deal about this curve?  It is just a curve."  You are mostly correct.  However, this is my FIRST flextrack curve.  The only curves I have laid before this were sectional.  So this is actually a big deal to me, and kind of scary since it has to align with a specific radius to make the plan work.  So go me for taking a new step!

So how did I go about making this curve?  Well, being an engineer by profession, I used my smarts (que laughter).  I built a radius tool and cobbled some supports together.  The tool is made using two nails, a screw, a pencil, and some leftover, small trim wood.  I nailed the pieces of trim together to be longer than the radius I needed (>42").  Then I drilled out a hole in one end and taped in a pencil.  On the other end I put the screw through the board at exactly 42" from the pencil tip.  Then I laid the board seen below on a shelf unit to act as a pivot point support.  Then I simply pushed the screw down in the board and ran the pencil between the straight lines guiding the main.  It worked like a charm.

Securing nails - watch out that they don't catch you.  They are pointy.

The pencil end.  What a quality taping job...

Now I need to finish the curve off.  I am following the recommended practices of connecting a soldering track as you go around the curve to keep a smooth connection point.  I will post again once that gets done.

And to finish things off, I want to start a new thing of ending posts with some proto shots I take on whims.  To start it off, below is PTRA 9609 crossing E Loop 610.  I got the shot while my wife was driving 70MPH so I am glad it came out as well as it did.  The unit is an MK1500D rebuild, and was hauling empty flats and gons from a pipe yard on 6/29/2014.

 

Until next time!

Tunnel Motor is Back Together

I finally have the T-2 back in running order!  The loco is much quieter now that it has the modern Genesis motor in it.  I haven't been able to test it against the other Genesis as that one is disassembled for detailing and painting now.  Really I am just glad to be done with the wiring.

However (as usually happens with me and the hobby) I created a new problem to solve!

Before I started, you could not see through to the other side between the air tanks and the fuel nozzle...  That area was all frame that I had milled out to fit the backwards motor.  Fortunately, it is only noticable from eye level as you can see below.

The camera was raised only a little and now the gap is invisible!  So I may or may not fix it.  We shall see.  Next for this loco is a little decal to show this engine is under ownership of the SRR now and some touchup paint.  Nothing too fancy.

I am also in the midst of planning to lay down the main line this weekend on the layout!  Finally!  I had everything in place and then I found I am out of rail joiners...  So after a quick trip to the hobby shop I can get started.  One the main is laid I will move on to designing the remaining layout portions so the roundy round can get started again.  I miss just having the trains run in a circle...

Re-Powering a Favorite

Howdy again!  This time I come bearing improvements that worked right the first time!

I bought an Athearn SD45T-2 a while back and I made posts on it and its progress here and here.  I finally got the replacement dogbone drive shafts that I mentioned last time.  If you recall, the model came with 1.609" shafts, and after putting in the new motor one of the drive shafts was short.  From what I could tell the best fix would be the 1.76" shafts.  Voila!  They are just right!  Below shows the shaft in the flywheel and gear tower.  It really is a perfect fit.

 

I gave the motor a few spins with the drivetrain fully assembled and I felt no resistance or binding.  So next up is to put the whole shebang back together and run it on the rails.  Hopefully she will run with the other Genesis locos well enough to consist them together.  Since I am finally going to join a club, I can really use the heavy haulers.

For a visual, here are the two different drive shafts side-by-side.

Check back soon as I will be updating with the performance of this over-hauled locomotive.

Making it modular

I have been slowly working on the layout these past months.  The biggest roadblock has been deciding the future of the layout.  We may be moving into a smaller house soon so I have been trying to figure out the best way to divide the layout into movable sections.  More on that other stuff later.

I had always planned on the layout being modular, as my wife and I's plan for our current living situation seems to be so fluid.  I built the frames individually, made track plans based the frame lengths, etc.  However, I went full bore on laying out the decking plywood and the track.  This turned out badly (read: stupidly) as cutting through track with standard cutting implements has proven ...difficult.  Most saw blades are too rough (too few Teeth Per Inch) and would tear the track up or separate it from the plywood.  So to make the layout "modular" I had to improvise ("as usual" he said disdainfully).

The biggest difficulty is cutting through the decking where track is already laid.  The best way I found was to cut the track was with a razor saw over where the modules meet.  Then I used a small drill bit and drilled through the plywood between and around the ties as much as possible.  The plywood was cut using regular hand and powered saws (the easiest part).  To finish it off, I used a hack saw blade to cut the plywood that was still connected beneath the track.  I would have used the razor saw but the blade is not deep enough to cut the track and plywood together.  I angled the hack saw blade in the existing cuts and slowly leveled it out as I cut upward.  It took awhile but it eventually worked.

 

 

So now that the layout is cut up, I can work on finishing the yard.  It works well right now but needs some tweaking.

For my final thought of the day: be sure that if you make your layout modular, you cut the decking before laying track.

Re-powering the Tunnel Motor is a Pain

So right now my budget doesn't allow much in the way of buying brand new locomotives.  I could if I saved up over time, but that doesn't work so well with me.  I plan on getting a new locomotive and suddenly "ooooo shiny new tank car!" or "well dang, I just got to have that Hy-cube" and etc, etc, etc...  So instead I tend to put a little bit into the existing engines.

In this case, I want to have my tunnel motor be able to run with my SD45-2.  This is the beginning of the Pain.  When I tried to do this a few months back (around September...  geez) I found that they were just too different speed-wise.  I played around with the speed table settings on their decoders but that was a lot of time to get nowhere.  So the idea was side lined.  However the idea has come back to the forefront as I am trying to join a local club.  But if they won't run well together then what can I do?

While the two locos are similar in drive train design, it turns out they have very different motors.  The tunnel motor is from the RTR line and the 45-2 is from the Genesis line, and the output on their electric motors is very different.  I had an extra RTR motor sitting around so I tried it in the 45-2, but the frame and weights will not allow it to fit (Pain).  So I decided to try a Genesis motor in the T-2.  After some time on the 'bay I got a new Genesis motor and went to install it.  Turns out it fits as far as the securing screw holes, but the frame was too tall for the screws (Pain again).  SOOOO more work.  Now it looks like this after some time on a mill.

One of the perks of working at a place with a machine shop

 

The motor now fits in the frame!  I had to add some shims into the securing holes as the screw heads could pass through them but it can be done.  However, I am now stuck again (more Pain).  To get the motor to fit, I had to put it in "backwards" so now one of the dogbone shafts is too short...  Blah...  There are some longer ones on order so I will update again when they are installed. 

If you want more detail on the process, or advice on how to avoid the pains above, leave me a comment and I will help out as best as I can.

Later!

Some Pictures for the Last Post

Alright y'all, are some pictures as I promised.

First is a shot of the layout construction progress. 

Aside from the messiness of the room, you can see how it is coming along.  About half of the decking of 15/32" plywood is attached and about 75% of the support frames are built.  I only have one more to go!

Due to space constraints I have scaled back the layout some.  It will now have three walls of layout and the fourth wall will be a connector for continuous running and where the work table will go.  However I do have a decent plan still.  The yard ladder has been built (it can be seen about halfway down the right side decking) and should be installed tonight if I can stay awake.

This is the re-motor project I am working on for the tunnel motor.  She didn't play well with my Genesis SD45-2 so I decided to put a Genesis motor in here.  The internet says that the Genesis motor fits RTR locos.  What they didn't say was that it takes some work...  More on that in a separate post.

And lastly, I randomly caught the Illinois Terminal heritage locomotive.  She unexpectedly passed me leading a train from the Texas City Terminal and by the time I caught up to her for a picture, this was the best I could do.  But I swear it is her!  Zoom in on the cab numbers!

And lastly, a shiny new BNSF Gevo near my work.

Now I am off to recover for an op session tomorrow on the Almeda Terminal & Gulf layout!

Workin' on the Railroad

Specifically my model railroad.

I have been making slow progress, but progress all the same.

I don't have any new pictures for this update yet.  I may put them in another later post.  Sorry.

Layout: work is progressing steadily.  I have all of the turnouts I need now so track will be laid in earnest once the layout is fully built.  One frame and the remaining decking to go!  Currently about half way on the decking.

Paint Scheme: a new Texas-themed scheme should be getting applied to a new loco shell next week.  I hope it comes out as cool as I imagine it as.

Prodigy: my trusty DCC system up and burned out on me a few months back.  MRC got her fixed up and returned so the engines can move a little at least

Yard: the yard ladder should be secured and powered by the weekend!  Once the ladder is tested and operational, I will lay the yard tracks and put out some rolling stock.

Until then, have a good time everyone!
