Fixing an Electrical Problem in a Locomotive
Craig sent in this question for readers:
“My LGB 251902-3 (2051S Cat#) will not pick up electricity from the rail. My smaller Furka Oberalp works just fine on the track. I have found that when I test the pick up plates, there is no circuit between the plates, meaning there is no voltage to the motors. It was working fine until just recently, but has been sitting on a shelf in my workshop for about 3 weeks.Any suggestions?”
Is the Passenger Vehicle in this Video a Bus, a Tram, or a Train Without Rails?
When I first visited China back in the 1980’s the cities were over-run by bicycles – there where millions! These days bikes are a reasonably rare sight in most major cities. Motorbikes and buses are becoming less common too. This is because cheap, efficient, safe, environmentally friendly alternatives are now available.
China now has the biggest network of high speed bullet trains in the world, as well as extensive underground metro mass transit systems under most of its major cities. As an example by late 2020, Shanghai will have around 502 miles (808 km) of subway lines servicing 500 plus stations… and that’s just one city! The metro stations are spotlessly clean with marble tiles etc, and trains run every 3 to 4 minutes in most cases.
Above ground, traditional polluting diesel buses will become even more of a rarity when these new transit vehicles that run on “virtual sensor guided track” become widespread throughout China. Some people say its a type of train on a guided track, and others would claim its are a type of bus, or tram.
What’s your opinion? Remember there are no rails in the traditional sense, but it still needs a track of “almost invisible” sensors for it to run on, so it can’t leave the line of track like a bus could. It also has no Catenary or Pantographs; so in your opinion is it a bus, train, tram, or a hybrid with no name? Add your thoughts below.
The 32 meters long and 3.4 meters high people mover, can carry 307 passengers with a top speed of 70 kph.
Instead of track, this passenger vehicle runs along dotted lines on the ground, controlled by hundreds of sensors. It also use rubber tires, which makes the journey like riding the bus. It uses Lithium Titanate batteries enabling it to run 25 km after just 10 minutes of charging.
How To Create Support & Protection For Portable Layout
Dan asks readers this question:
“I am currently putting together my first portable layout to display on Canada Day. I am using two 2×8 foot pieces of 2″ styrofoam SM as the layout surface which will run two separate oval tracks. My current struggle is designing a frame that the styrofoam will sit inside of and hold all together plus provide a No Touch zone and derail barrier. I do not plan on adding legs at this stage as time is limited. I will be setting it up on some fold out tables at our town hall.”

Problems With Peco Turnout Motor
Asa models N scale and asks readers:
“ I have Peco turn out motors. And I have attached to the bottom a switch that controls dwarf lights. When I hook it up to the ac side of my transformer it works fine. When I put the turn out track on it does not work at all. I pulled the little spring that keeps the points in place and it went back to work fine. I’m I doing something wrong or could my transformer be weak or is there something else I should be doing? I would like to keep the spring because it does a very go job of holding the points in place. the ac voltage is 20. ”

Do You Need Blocks with a DCC System?
This article kindly contributed by club member Jim P.
If you grew up with a DC system, then you will be familiar with the term “Blocks.” Having blocks on a DC model train layout is basically the process of separating the railroad trackage into sections, so as to control one locomotive independently of another loco in a neighboring block.
If you think of how real railroads operate, they typically divide mainlines into blocks, which are assigned signals to keep railroad traffic on the right track and at a safe distance or separation.
The question that often gets asked is, “Will I still require blocks with DCC?”
In theory you won’t need blocks as in the conventional sense. However, with DCC systems, blocks are regularly utilized to operate signal systems as well as to isolate problems. Blocks are necessary when using block detection, or polarity reversing sections i.e. wyes, turntables, or balloon tracks which are like a big loop tracks with a single switch to enter and exit. It’s worth noting that a reversing section will need to be at the very least the length of the longest train. This is especially so, if the train has passenger cars, or a lighted caboose.
Read more on DCC wiring techniques here…
Blocks for that purpose might be sufficient on some small model railroads, but incorporating more blocks would be beneficial on bigger layouts. Having additional blocks would certainly prove an asset on a layout operated by more than one person, or for one that is larger than would fit onto a standard sheet of plywood. Take it from me… it is so much easier to troubleshoot and isolate problems with blocks in place.
That said; a typical DCC layout won’t usually require as many blocks as would have been necessary on a conventional DC layout, but having some blocks will at least make it easier to locate and fix problem that might otherwise be difficult to pin down. Besides, without having blocks it might be necessary to shut down the entire DCC layout if there’s a short… and that not something any of us would want to do.
Power Source for LED Lighting

1970’s Railroad on Show
It’s always great to see some scenes from yesteryear. These photos of 1970’s commuter trains were sent in by Alexander who shot the photos at the Sydney Model Train Show.
Upper Level Track Clearance And Gradient
Shane models HO and asks readers:
“I want to run a double track to a proposed new upper level on my 4×9 setup and want to know how high to make it above the lower level. I don’t want the gradient too steep but still want enough clearance for access and for trains to run under the top level. Sorry if that sounds confusing.”
Changing Snap-In Rapido Couplers to Knuckle Couplers
Graeme operates N scale and his question to readers is:
“Hi guys i recently bought a few Fleischmann carriages with snap in Rapido couplers, I would like to change them to snap in knuckle couplers. I found some but don’t really want to pay $100 for 5 couplers that includes post from England to Australia, I think that’s a bit over the top. Any ideas?”

Loco Made Using a Stanton Drive 4 Wheel Truck and Dummy
Reader Robert models HO and asks this question:
“I have made a loco using a Stanton drive 4 wheel truck and dummy. It runs OK on the flat or running up grade, when descending grades it runs with a very jerky motion. Any suggestions on how to remedy the problem?”

Powering LED Lights for Passenger Coaches
Schalk models N scale and asks readers:
“I want to install LED lights in my N Scale (DC) passenger coaches (Atlas, Bachmann, Model Power, etc.) without using power from the tracks. I want the lights to remain on when a train is stationary (waiting for signals, standing in a station). Is there an easy way to install LED’s with their own power source in passenger cars, and most importantly how can they be switched off? Thanks.”
Using Crushed Limestone Parking Lots and Roadways
Richard sent in this question for readers to comment on:
“I have been using ‘Chicken Grit’ to form side roads and parking areas around grain mills, and other rural buildings. The ‘grit’ is usually mixed with chicken feed since they need a form of ‘grit’ to aid digestion. Grit can be granite, sea shells, etc that is ground, however I have been unable to find small enough grit (HO size) in familiar yellow/brown colors of crushed limestone used here in upper Midwest of USA. Thus I have had to airbrush the grit to the proper color and then when dry (had to spread to paint) then collect and spread on a base of white glue and water to allow it to adhere to the sub-base of lot or roadway. Just wondering if/what others might use to obtain similar lot and road cover in the light yellow/tan color. Most grit is a bit too large and sand seems a bit to fine. Thanks for any comments of suggestions.”
