  1. Track Electrification

    Several years ago I posted about my project to build the Windhoff MPV. I updated the post last month with a few pics of the almost completed models. The models depict the electrification of existing train track for running of electric trains. The whole build project has been inspired by the electrification of the Great Western Trail Line in the UK using the Windhoff MPV. Last weekend I attended the Brick Event on the Gold Coast (Queensland, Australia). The table was a bit cramped but by talking to the public they were able to see the design and function of the machines. By the end of the first day talking to my table neighbour he convinced me that the 2 tables wasn’t enough for the display so to the floor I went. Originally I was going to build two MPV’s, but during the process I increased the build to three with the third having a container style build with some nice snot construction techniques for the drivers cabin. I was quite happy how this turned out. The Windhoff MPV’s were fun (even if it took me a while) to build, especially since I went 8-wide therefore creating the scale of 1 stud = 1 foot. This gives the models great detail and sense of scale. I coupled the MPV’s with a wagon using the same scale. The MPV’s feature ISO locking points at 10’ intervals and a small knuckle boom crane at the trailing end. The substructure detailing was fun to create, trying to get the detail right balance between ease of build (using the parts I had), Lego geometry and accuracy. I was able to get during the build a couple of 1x4 light grey tiles with a text on them looking like a serial number or build plate. At 70 studs long (buffer to buffer) I was unable to get the bogie set to rotate as it is fixed to the sub-frame structure, so running it around the track is a no go for me. The coupled wagons are 70’ (buffer to buffer) long at have ISO coupling points for 3x 20’ or 2x 30’ containers/pallets. I’m not 100% on the real world bogie spacing but again they are fixed and offer no rotation. As part of the display I had previous built MOW equipment (trucks and the work wagons created by other talented individuals) showing the electrification process. I designed my own catenary system and while I’m happy it has room for improvement. Stage 1 – footings The Robel Bullok and trucks prepare the site and the footings. Stage 2 - mast MPV #1 is configured for mast installation with a stylized cab, 10’ tool room, a frame for mast storage and a long reach crane. Stage 3 – minor structures MPV #2 is configured for minor structure installation with a stylized cab, 10’ tool room, a 30’ pallet with an elevated work platform, and knuckle boom crane. Coupled to this is a wagon which holds plenty of catenary structures and a knuckle boom crane. Stage 4 - Wiring MPV #3 is configured for wire installation with a snot container style cab, a 30’ pallet with an wire dispenser spindles and a knuckle boom crane, a 10’ section for more spindles and again a knuckle boom crane. Coupled to this is a wagon which has a 30’ pallet with an elevated work platform, and a 30’ pallet with a 24’ scissor platform. Stage 5 – testing The Plasser & Theurer MTW100 measure test and adjusts. As can be seen in the pics I used twisted wire. It was a great idea that didn’t pan out as I expected with too much twist and rigidity and the real stuff is held under tension which isn’t possible with my display. I have brought some other wire which will stay straight thanks to the youtube video hack.. There are plenty of small improvements to be made, but then no one is ever 100% happy….LOL None the less please enjoy the pics and let me know what you think.
