Every now and then there are some articles online on one of the well-known fora that you just HAVE to share to a broader audience. A while ago my eye fell on an article by Hod Carrier over at the Train Tech forums of Eurobricks. Hod Carrier is no stranger here at BMR, having contested twice on OcTRAINber, and one time almost. Today we present his second part about Trackside Structures, one of my favorite parts of any realistic Lego Train Model Railroad:
Thanks so much for the fabulous feedback that I’ve received so far. It’s really amazing to have prompted such a response.
I’ve been busy adding a few more details which I hope you won’t mind me sharing. Don’t worry, though. I’m not intending on reproducing every single piece of UK rail infrastructure.
In order to reduce noise and wear to rails and wheelsets, flange lubricators (sometimes referred to as grease pots) are provided because, lets face it, no-one likes a dry flange. *Ahem*. These automatically apply a small amount of grease to the train wheels as they pass to help reduce friction. These are often found in areas where the route follows tight curves or at junctions.
When clean these are generally yellow to make them visible, but over time, and through careless refilling, these eventually become black.
Very simply, this is a drain. At some locations the ground or environmental conditions means that the ballast and formation of the track is insufficient to provide adequate drainage. In this instance additional drains are provided, either at the sides or between the tracks. I won’t insult anyone’s intelligence by showing the design in isolation, as I’m sure it should be clear.
This is a Hot Axle Box Detector (HABD) together with it’s associated small portable-type lineside equipment building. These detectors are dotted around the network and are used to detect an overheating axle box. These automatic installations sound an alarm at the signalbox and tell the signaller which axle and on which side of the train the defect is occurring so that the train can be stopped and examined.
The central detector between the rails is offset to be nearer one rail or the other to help the system determine which side of the train the defective axle is.
There are many different designs of point/switch motors in use across the UK, and this is just one of them. It is an older design that has since been superceded but which remains in operation in large numbers across the network.
The design does not affect the operation of the switch and should not interfere with passing trains either. I would have liked to have had a go at one of the successor designs, but the studless nature of the standard LEGO points/switch preclude this, although third party offerings may be different.
All of my designs so far have been made to be compatible with the PennLUG ballasting standard. While it’s great for LEGO modellers by being compact and not too demanding in terms of parts, I don’t think many operational railways would tolerate such a shallow bed of ballast. Certainly in the UK the trackbed is much wider and ballast shoulders are built up at each side.
I suppose you could call them shoulder pads in that they bulk out the track ballasting to more realistic proportions. There are side sections and centre sections.
Used together for a twin track arrangement (as in the previous picture) the total width comes out at 34 studs, two more than a standard 32×32 baseplate. Consequently I have shown the design split across two baseplates with the centreline as the join. To make this compatible with the MILS modules, the centre section is built in two halves to facilitate splitting of modules into individual 32×32 sections.
