CLTC wishes a Merry Christmas and the very best to all for 2022. Here is a quick photo of Sue’s Christmas train beneath the tree and her cat Milo watching.

Lego Set 65524 & Christmas Tree

Emerald Night Connecting Rods

The Emerald Night, LEGO® CREATOR Expert set 10194, is a favorite among LEGO Train fans… definitely in the top ten and maybe even the all time favorite to date as a set. There are a few minor flaws that have been discovered in this sets design, including the piston push rod support, the rear floating wheel set and the motor gear support; these were listed in the excellent magazine RailBricks.

As our club uses many of our locomotives at Train Shows where we run through other people’s displays, we have a standard that trains are to be less than ten studs wide. The Emerald Night is exactly ten studs wide, but when station platforms have a ten stud gap, there is not sufficient tolerance for the trains to pass through the station reliably. Additionally, the Emerald Night looks bulky with traditional Technic based connecting rods.

With advances in 3D printing, we took it upon ourselves as a club to come up with a push rod design that we could 3D print. Information can be found on Thingiverse. We are very pleased with how this turned out and are looking foreward to post COVID-19 where we can try it out at a Train Show.

Motorize LEGO 7810 Locomotive

The 40th anniversary LEGO commemorative set 40370 to bring back set 7810 is a very clean, simple build. The locomotive has a classic simplicity to it that makes it appropriate for any railway display, and it has a nice six-wide / mini-figure scale that works. The new train comes as a push train with brick built buffers where as the old train was built on a custom modified chassis plate, element 4178, which getting increasingly hard to purchase.

There are a couple of people that have motorized this set either with a medium motor in the steam drum or by pushing the train with a motorized coal tender. I thought I would share how I motorized this locomotive using five (5) small eight tooth gears (3647) connected in row on a technic five hole lift arm (32316). Using a the three stud wide technic connecting pin (6558) to connect the lift arm at the top of the motor and a 2×2 modified plate with two pin holes (2817) near the bottom provided adequate support. This also allowed all three wheel sets to be geared together so that they all were turned by the motor.
