Article by Conrad Schlenker
In the past, we have seen great and highly informative articles from Hod Carrier and Matt Csenge on simple but good-looking details anyone can build to add detail to their track. Today, I’d like to do the same, but for a relatively unexplored genre of L-gauge modeling: Light Rail!
Light rail is a very important mode of public transportation in a lot of major cities throughout the world. Although I will be covering details that aim to replicate things found in America, hopefully this article is helpful to anyone looking to model a rapid transit railway.
Before we get into the larger details, lets look at some simple details that don’t take many parts, but can add a lot of detail that is sure to catch any spectators eye.
Tie Choices
I 100% agree with the things Matt said in his 2nd article about USA Track Detailing. Ties are everything. Concrete ties are quite common on light rail systems, so here are a few ways to do them:
Concrete ties left to right:
- Dual block ties with no fasteners
- Dual block ties with 1×1 plates for fasteners
- Full concrete ties with no fasteners
- Full concrete ties with fasteners on both sides
- Full concrete ties with fasteners on outside only
Its also recommended that you put ballast in between a double track mainline as well.
Trackside Signs
Whistle Board. Used at grade crossings, it alerts the driver to use the horn in order to warn motorists of the incoming train.
Absolute speed board. Tells the driver the current or absolute speed limit of the track.
Upcoming speed board. The slant of the board indicates that the speed listed on it will be in effect when the next board arrives.
End of Track Bumper
There are many different types and designs of end of track bumpers out there, but this one is modeled after the one used on the DART system, which is the closest light rail system to me. Rest assured, this detail will look great on any layout, and looks general enough to match other designs seen all over America. The end of track bumper is obviously used to stop a train from going too far off the rails when its going too fast. Sometimes it works better than others, as seen in an incident in a Chicago Metro station a few years ago. The bumper is attached to the rails, which is modeled by the 1×4 plates in between the ties, and the 1×2 jumpers hanging over the rails. Also modeled are the rubber pads, which are meant to soften the impact, but don’t really help much if the train is going fast enough to hit the bumper in the first place. I used 1×2 grills for these. Since these bumpers are so common on light rail / rapid transit lines, this detail will bring a lot to any layout, and is sure to catch the eye of any spectator.
Next, we have a simple line side signal that can be found pretty much anywhere on a light rail system. Signals are necessary not only to light rail lines but any type of mainline anywhere in the world. Their job is fairly simple and works much like a traffic light on a road. It tells drivers weather or not it is safe to proceed, and if anything is occupying the right of way in front of them. The most common aspects seen on such signals is as follows: Green or clear = proceed at line speed, flashing yellow or approach medium = proceed with caution and be prepared to stop in the next 2 signals, yellow or approach = proceed at a maximum speed of 40 miles per hour, and be prepared to stop at the next signal. There are many more aspects, meaning lots of different things, but that should give you a basic understanding on how they work. Light rail signals appear more box-like than signals found elsewhere. It is important to make sure the signal looks like it is set in concrete, hence the LBG bricks at the bottom. This also goes for crossing gates and catenary poles. Some signals have two ‘heads’ on them, which means they display two aspects at one time. The second head can easily be built under the first one if you need it.
Don’t worry, this detail is compatible with the PennLUG style of track ballasting found on L-gauge.org. Light rail lines often have to weave through small spaces to get where they need to go, so on especially tight corners an inner 3rd rail is used to make absolutely sure the train stays on the track. It’s not like the 3rd rails some of you may have heard of; it doesn’t provide power on the outside of the track, it provides stability o the inside of the track. These can be seen in maintenance bases, yards, and on the mainline, as well as be attached to either the inside or outside edge of the rail.
That was my last detail for this article, and although it was a short one, I hope it gave you some inspiration and jumping off points if you ever take on a project involving light rail. If you’re wondering why I didn’t talk about a catenary pole, its because the height usually changes depending on the scale of the train, and I didn’t want to create a size limitation for people who don’t build the same scale as me.
To all who read this far, thank you. I hope you enjoyed this brief look into the world of light rail.
Play well,
Conrad.
