Framing the NEW New Boston and Donnels Creek RR, Part 7

This is a followup to Part Five of our series "Planning the NEW New Boston and Donnels Creek RR," being written in conjunction with other construction and planning articles that tell the story of our "new" railroad in chronological sequence, beginning with planning efforts in early 2017.

At the end of the last article, I had finalized plans for half of the last and lowest layer of the planned right-of-way.

If you've been following us from the start, you know that the lowest layer of the railroad will wrap completely around the right-of-ways I've built so far. However, the way it is designed, it can be built in two parts.

In this article, I began building the extension on the east side of the railroad. I can build the other extension later, since the only things connecting them will be a storage track running through the shed and a bridge across the third connecting pool.

The addition shown as an 8-post raised railroad. Click for bigger photo. A detail of the plan from the previous article is shown to the right. The parts of the railroad that are already built are shown in gray. The existing posts are shown in orange; the new posts are shown in brown. The joists are shown in black and the frame that will support the decking is shown in brown.

Digging Again - Last spring I bought a gas-powered post-hole digger/auger from Harbor Freight and used it to dig eight post-holes in a part of the yard that has a great deal of gravel, etc. The "Predator Gas-Powered Earth Auger" worked fine. Then. Though I followed the instructions for maintenance and storage scrupulously, it won't start now. Here's something else to know - When I gave this a low rating on the Harbor Freight web page, they deleted my review. Now you know how they manage all "four-star" and "five-star" reviews on their products. Anyway, that one is going back. (I have bought other tools from them that work fine, but sometimes you do get what you pay for.)

Fortunately, the ground where the next holes needed to be dug is just clay with very few rocks or other obstacles. I got out my manual post-hole digger and a ditch shovel and got started. The ground was so hard from the drought that after I went down a few inches, I filled the holes with water and went back later to finish, just as I had on the hole for the in-ground pond. It softened the clay enough so that the five new post holes were no real problem to dig.

Posts Installed Because our frost line is reputed to be 24" deep, I cut 4"x4"x8" posts in half and sank them into the new post holes. In the photo to the lower left, you can see that the post closest to the waterfall seems to be shorter than the others. That's because the ground is lower there. All the posts are a tad longer than they will need to be because it's much easier to shave a few inches off a post that is installed than to make one taller.

The photo to the lower right shows the hole I cut into the side of the train shed to allow a joist to reach a post just inside the wall.

The five new posts installed.  Click for a bigger photo. The hole I cut into the side of the train shed so I could attach a joist to the post just inside the corner. Click for a bigger photo.

Joists Installed - Next I installed the joists (lower left photo). For the most part, I attached them between new and old posts. When planning a structure like this, remember that the joists usually run the same direction that the decking runs. (The frame that supports the decking will run perpendicular to the joists, and the decking will run perpendicular to the frame.)

The maximum span recommended for a 2"x6" deck joist in this part of the country is usually 6'. I used that span on the longest joists, but I also ran the joists past the posts about 11" so that part of the frame could extend a bit farther out. You may also notice that I ran the two center joists farther back under the railroad than I "technically" needed to, just to provide a little more stability and strength to the structure.

Notching the ends of the joists isn't necessary. To me it just dresses them up a little.

By the way, getting the joists level and level with each other is the hardest part of doing this by yourself. But once you've done that, the rest of the project is relatively simple.

Once the joists were installed, I cut off the top of the posts, leaving about 4" on each (lower right photo). That would be enough to attach some of the frame bits to if I wanted to, but would allow the decking to go over them without interference. If you accidentally forget to do this until after the frame is installed, you will find yourself doing some difficult cuts or overusing your reciprocating saw.

The joists are installed on the addition to the NEW New Boston and Donnels Creek railroad. Click for bigger photo The posts trimmed to protrude no more than 4

Framing Considerations - When room allows, I run the frame pieces 2' apart, since that's the maximum recommendation for frame that will be supporting 2"x6" decking. The decking will run perpendicular to the long frame pieces, of course. It will also hang out over the end a bit.

Note: If you use ordinary "5/4" decking you should consider running the frame boards 16" apart. Again your state may have different recommendations.

Because of having to fit the new platform around existing structures, I couldn't do the framing exactly the way I would do it for a freestanding structure. So there are several places where the frame boards that will support the decking are less than 24" apart. But of course, that just adds to the strength of the platform.

Laying out the track I am considering using on this addition to make certain my framing will accommodate it. Click for bigger photo. Once the frame is covered with decking it's too late to make major structural changes. So I laid out six pieces of the 10' diameter track curve I was hoping it would accommodate to be sure I had allowed enough room. The squarish part of the frame is 11' across, so there is plenty of room there. Once the decking is installed over the diagonal bits, there will be plenty of room there, too.

Eventually (when the other expansion is installed):

  • The left end of the 10' curve will go onto straight pieces and go right into the train shed. From there, it will go through to the other platform, which is not built yet.

  • The right end of the curve will actually have one piece less than shown in the photo. It will go into straight pieces and across the lower connecting pool. From there it will go to the other platform (which is still not built).

The little 4' circle is there because:

  • I'm considering having a little trolley line or some such on that platform, too, eventually.

  • In the meantime, I am planning on putting a loop of track there temporarily to run a train on during our "Christmas Train Day" in November, and I wanted to see how big a loop it would support.

I trimmed the right end of the frame boards to make it easier to see the waterfall from the back porch.  Click for bigger photo.I realized at this point that the right side of the frame would obscure the third connecting pool a little more than I really wanted it too. And since I had more than enough space there for my track, I trimmed the framed boards there by a few inches.

I realize that a more precise planner and builder would have seen that ahead of time and avoided the "last-minute" correction. But, again, things like that are a lot easier for me to see as the structure is taking place.

Depending on how things work out when the next extension goes on, I may build a trestle to cross the third connecting pool. But in the meantime, there will be some simple plantings and mulching around the pond to make things look a little more established before the next open railroad.

The following photo shows the rest of the frame installed and ready for decking. Yes, I put the track away again before I started that effort.

A Note About Temperatures - You may have noticed that the clock in some photos is never showing a time that makes sense considering what else is going on. That's because three straight months of 90 degree temperatures have destroyed the batteries in it twice, and I'm not putting new batteries in until it cools down.

Also you may have noticed that the bird feeders I set on the railroad for the winter are still out and my nice custom buildings are nowhere to be seen. Again, even though I have protected my custom buildings against reasonable UV and temperatures, three straight months of 90 degree temperatures would have caused so much damage I would have had to repair or repaint them before my next open railroad anyway.

At this time (early October) we are still getting temperatures in the 90s, at a time I would ordinarily be thinking about being ready to protect my tomatoes from killing frosts. Please let me repeat what I have said earlier - never tell a gardener that global climate change is a hoax.

Conclusion

I actually got started on the decking the same day I finished the framing, but this article was getting long enough. Plus I ran out of lumber before I had enough of the platform decked to make it worth photographing. Stay tuned. In the meantime, I hope I've given you enough information to inspire you to think "outsided of the retaining wall" for your next garden railroad endeavor.

Keep in Touch

Finally, please let us know about your ongoing projects. Ask questions, send corrections, suggest article ideas, send photos, whatever you think will help you or your fellow railroaders. In the meantime, enjoy your trains, and especially enjoy any time you have with your family in the coming weeks,

Installing the in-ground pond and preparing to install the last connecting pool to make our waterfall complete.  Click to go to article.Return to "Planning the NEW New Boston and Donnels Creek RR - Part 5" - Once the major components of the water feature were installed and tested, we decided to add one more bit of railroad proper before our "Christmas Train Day," this November. The addition, about 5'x11', will allow us to put a small train and some scenery closer to eye level for youngsters. Eventually it will be part of the larger plan that will allow us to run our bigger cars and locomotives.

Weather permitting, I often worked all the live-long day. This article describes installing two posts that will eventually support the last connecting pool, then digging the big hole for the in-ground pond, complicated by a three-month drought that turned the ground to concrete.

Click to go to articleReturn to "Adding a Train Shed Part 1" - What started out as a simple addition of a deck to stand on when putting trains on the track got a little more ambitious when I realized that JUST installing the deck this year would require more work next year. So we framed out what we planned to be a train shed attached to the railroad. If it ever gets finished, I can easily put trains on the track at a moment's notice instead of schlepping them out from the garage.

I also decided to frame out the top railroad layer while I could still access the center of the railroad easily. Because I was running out of vertical space, I reconfigured that layer. Then after I got the "core" pieces on, I changed my plan again. But the whole thing is getting easier and easier to visualize, and is getting closer to complete with every board I cut and fasten on.

Now the folks driving down the street past our house (we're on a corner lot) probably wonder if I'm building an elaborate chicken coop, but that's fine with me. I still need to make a few more lumber runs and do a lot more cutting and sawing, but having the basic frame in place should make the next bits a lot easier.

Click to go to articleReturn to "Planning the NEW New Boston and Donnels Creek, Part 4" - Well, the rented post-hole digger fell through, so we dug our vegetable garden with a manual post-hole digger (the scissors kind). In addition, I stake out where the railroad was going to be. Twice. And tweaked the plans again. Sorry about the redo's, but sometimes just walking around the yard trying to visualize things makes me reconsider something that seemed "settled" only a few days before.

Click on the photo to see what we were considering as of late May, 2017

Click to go to articleReturn to "Planning the NEW New Boston and Donnels Creek, Part 3" - We have still not broken ground. In part because we plan to rent a post-hole digger and dig the post holes for our raised vegetable garden and the first phase of the garden railroad at the same time, and we don't have enough lumber on hand yet. (If we didn't break it down into multiple trips, we'd be blowing out the shocks on our minivan.) In the meantime, we used a line level to see if the slope of the back yard was as bad as we thought it was (it's worse), and we did other site preparation, including planting a whole bunch of spruce tree seedlings to eventually give us some privacy in our side and back yard. Plus, I'm still wavering a little on the "where-to-start-first" issue.

Click on the photo to see what we were considering as of late April, 2017

Click to go to articleReturn to "Planning the NEW New Boston and Donnels Creek, Part 2" - More plans. We've moved on from the 2"x6" roadbed-on-posts to a sort of "train-table-outside" plan. Our goals include low-maintenance, high interest, and high reliability. We're also trying to get around having a thousand dollars' worth of dirt hauled into the back yard. If you want to get some idea of what our planning process looks like, reading these through in sequence may help. Or it may drive you crazy.

We also left behind a high-maintenance garden that we do not intend to replicate at the new place. This is the first chapter of a new chapter in our lives, which we hope will include a lot of "lessons learned." But first, some serious landscaping had to take place.
