Untergroeningen Outbuilding (3)

 [ Untergroeningen posts ]

[ part 2 ]

With the drawings done and checked, it's time to go to the workbench and pull out the styrene. I first had to take care of and clean up a couple other projects that collected dust there. Once that was out of the way, I started with building the core of the outbuilding.

The NWSL True Sander is very useful to get the edges straight and at ninety degree angle. Working on a glass tile helps with keeping the pieces aligned.

Untergroeningen Outbuilding (2)

 [ Untergroeningen posts ]

[ part 1 ]

I finished the outbuilding drawing from yesterday, made copies and built a paper mock-up to verify appearance and scale. The proportions are slightly off from the original, but close enough that I'm not going to worry about it. I like how the building is coming together.

I tested placement on the module. When I compared the photo below to photos from the prototype, the placement is a bit too close to the station building. However, there's enough space on the module to move the outbuilding a bit further away and still have plenty of space for the wooden shed from the prototype.

Solar System Check-In

Back in March I mused that summer production with the new inverter should produce a nice rounded curve with the sun higher up in the sky. And indeed it does.

After months of waiting, the Tesla Gateway has finally arrived. As much as I dislike the Tesla app, and Tesla's decision to make the app the only place where one can access the solar system's data, it is nice to check in on production from the comfort of the couch.

Untergroeningen Outbuilding

 [ Untergroeningen posts ]

My next project is scratch-building the outbuilding at Untergroeningen station. As was common for lines built before and around the turn of the 19th century, the public restrooms were in a building separate from the main station building. In Untergroeningen, the building also includes what looks like a garage, or storage room.

Vergessene Bahnen has several photos of the Untergroeningen station area and its author shared additional photos with me. Thank you, Herr Schruft! I'm using the photos to draw up plans for the building. The guiding idea here is to get the scale right in relation to the HO figure, and approximate the building outline and features as closely as possible. I have clear photos of three building sides. The right hand side is hidden in the shadows of the tree next to the building, so there's some guesswork involved.

Next up is making copies of the drawings, putting together a paper prototype to put on the module, and checking scale in relation to the other buildings.

NMRAx: "Remote Operations at Silicon Valley Lines"


Dave Falkenburg and I gave a talk about remote operations at Silicon Valley Lines as part of the NMRAx clinic virtual convention program. The edited version of the talk has now been uploaded to Youtube. I'm very happy with what we at Silicon Valley Lines have managed to build here, and how the concept of remote operations is gaining traction, likely to stay with us as part of the "new normal" post-COVID.

Coos Bay Rail Link (CBRL) behind the bushes

After yesterday's more detailed post, here's a lucky snapshot from the moving car through the bushes.

Friday, April 23, 2021

Coos Bay Rail Link (CBRL) Local East

From Florence, OR to Eugene we took State Highway 126 which mostly follows the Coos Bay line to Eugene.  As luck would have it, along the way we passed the CBRL Local on its way to Eugene. We drove ahead a bit to get on the south-side of the train at Central Rd, halfway between Veneta and Eugene. I knew I was not going to get a great shot, but at least I wanted fully lighted locomotives.

In the lead was CBRL 1859, an EMD MP15DC switcher. This locomotive was built in 1982 for the Missouri Pacific, came to Union Pacific through merger acquisition, and was eventually purchased by CBRL in 2018.

CBRL 2018 is a GP38-2, built in 1965 for the New York Central and came to CBRL from Union Pacific in 2019. The train today consisted of a couple two-bay hoppers, about 10 empty log cars, and more than 20 loaded centerbeams.

l don't know how the operation on the Coos Bay line works. Based on what I'm seeing in this train, I'm guessing the log cars come loaded out of Eugene Yard and moved to the Seneca sawmill in Noti, OR, where they are unloaded, returning empty. The centerbeams would come loaded from Rosboro Lumber in Vaughn and  Seneca in Noti. Unfortunately, I didn't take a photo of the product label of the packaging, so speculation has to suffice. I did notice that centerbeams in the middle of the train were loaded with unwrapped stacks of 2x4s, while the centerbeams in the rear were loaded with packaged wood products.

After the train had passed us, we caught up with it just as it was crossing Coyote Creek. This was an unexpected and fun chase.

Coos Bay Rail Link (CBRL) North Bend

CBRL 1909, a GP30, tied down in North Bend

The Port of Coos Bay purchased 134 miles of rail line between Coos Bay and Eugene in 2009 after the Central Oregon and Pacific (CORP) shut down the Coos Bay line with no advance notice in 2007. The port is now operating the line as Coos Bay Rail Link (CBRL) with a fleet of second and third hand locomotives. 

As we drove on US101 through North Bend on our way to Florence, OR, we stopped at the CBRL office because Patricia saw locomotives from the road before me! While I took a few photos she grabbed Fish&Chips at The Boat, which is conveniently located right across from the CBRL office.
CBRL 1916, a GP38-3, is also tied down in the yard

The Oregon Coast Historical Railway Museum is right next to the rail yard. Looks like a work of love. Sadly nothing's going to move here again. The tracks in the museum have no connection to the yard rails.

NWP near Geyserville

There are still tracks on most of the right of way of the Northwestern Pacific Railroad which was formed jointly by the Southern Pacific and the ATSF and used to run from Sausalito to Eureka. Present-day SMART is using the southern end of the right of way for modern passenger service and maybe the section in the photo might see passenger service again in the future.

For Easter weekend we went on a two-night trip to Yosemite. We stayed at Curry Village and hiked the Mist Trail all the way to the top of Nevada Falls with the detour via John Muir Trail and Clarks Point.

Lunch on top of Nevada Falls never tasted this good.

The crowds were plentiful at Vernal Falls and the lower section of Mist Trail. We still enjoyed it the scenery and had some fun.

On the second day we hiked half of Four Mile Trail which offers spectacular views of the other side of the valley.

In the evenings we hung out in a meadow and watched the sunset. A great trip!

Coyote Ridge Hike

The Santa Clara Valley Open Space Authority opens the Coyote Ridge preserve at the east end of Bailey Rd only a few times a year. Normally, they only offer docent-led group hikes. However, due to COVID they switched to a reservations-only model and we got to enjoy a self-led hike with very few people around us. We used the opportunity to take it very slow and enjoy plants, animals, and the views. 

The climb from the parking lot to the top of the ridge via the switchbacks is strenuous, but spectacular due to the wildflowers in full bloom and the many Bay Checkerspot Butterflies.

The trail along the top of the ridge meanders between the rolling hill tops, and has some nice views. It's mostly flat and provides some welcome respite and variety.

A great way to spend a Sunday morning.

SVL: March Ops

CabCams tested and ready to go

With Santa Clara County back in Red Tier we started to plan for an end of the month remote ops session. This week the county upgraded to Orange Tier and California announced availability of vaccinations for everyone in April, so things are definitely improving with regard to the pandemic.

This month's Ops was for club members, and became sort of a shake-down session. The layout hadn't run since the November Open House, and we wanted to try out using Zello Personal instead of FRS radios to facilitate remote operator communications with Dispatch and Yards, including the ability to have multiple sub-channels for focused communication.

Extra 200 is staged in Dodge Siding for a trip to Tracy

Somewhat to my surprise, we had a lot of problems with Zello. The app is very slick, and easy to use. It does project the feeling of being on a radio link, which I think adds to the realism of communication.

However, multiple participants reported problems with a significant delay of the microphone going live, as well as being throttled by Zello for sending too many messages. It's not a good situation when the dispatcher can't talk to the rest of the crew because Zello determined that he has been too active and repeatedly puts him into a "timeout box" for two minutes.

I spent a good part of the evening jumpstarting the session. When the crew settled into a rhythm and the session was running, I got to run train 443, which required a local operator due to the large amount of switching needed in Nowheres and Silicon. After being in a session facilitator role for most of last year, it was very nice to again run a train on the layout.

Train 443 (in the front) has suspended switching in Silicon to let Extra 200 pass. X200 is controlled by a club member in the UK.

With switching chores in Silicon completed, train 443 continues to Windsor

Overall, this was a good, but somewhat chaotic return to operating our layout. There is a Youtube Live recording with sound from the dispatcher channel which might be enjoyable to some of my readers.

Morning Hike on Fortini Trail

We're using the last few opportunities of free entry to Santa Teresa County Park, before parking fees kick in again on April 6th.The park is particularly nice at this time of year. The grass is greeen, the poppies are out, and the wild turkeys are roaming around.

Solar System Refresh

Back in 2007, we installed our rooftop solar system. The SolarCity installer told us that we should plan on replacing the Xantrex Inverter after about 10-12 years. It lasted 13 years and finally died last fall. Tesla gave us a pretty good deal on a replacement inverter and in early February, our new Delta inverter went online.

I'm still waiting for the Tesla gateway to arrive so we can set up remote monitoring. Meanwhile, I'm checking in on the system from my phone using the inverter's Bluetooth connection. The app I use is called Delta M Professional. It is quite bare bones, but gets the job done. Our system is still producing 3 kW at peak, the panels are holding up well in year 14. In the afternoon we have some shading from one of the trees in the backyard, hence the uneven downswing of the power production curve. This will get better in the summer months when the sun is higher in the sky during the afternoon.

Yesterday was a pretty good day with clear skies and we produced over 18 kWh, which is roughly inline with March historic production.

Published. Again. (2)

Part Two of the article series Jeff and I wrote for Roundhouse, the magazine of the NMRA British Region, was been published recently, and today our printed copy arrived.

Part Two focuses on the practical aspects of setting up and running the November 2020 Virtual Open House at Silicon Valley Lines. The technical setup, practical considerations for tools and software, as well as ensuring a positive visitor experience.

Hopefully, we'll be able to offer a similar event to a global audience very soon.
