I've made another 12v layout video, and this one includes an inner and outer loop, electrically connected through the points. The last clip took a couple of tries to film, since I had to do some quick point work and the trains collided in the first takes. These posts have been getting a lot of nice comments which means a lot to me as a content creator, and I'm glad people are enjoying my videos! I also have an extra clips video and a behind the scenes video, which I'll post links to in this thread as they release. Enjoy Layout 7!
Paperinik77pk posted a topic in LEGO Train TechHi all, since I read the very, very interesting thread about Torben Plagborg creations, I've been trying some new designs (some are just sketches, just to understand how things could work). Now, in this nice thread some nice 12v creations can be seen - but one captured my interest more than others. It's a little blue steamer with a black 12v motor. It seems pretty big, so I'd say it was an 8-wide experiment. In general, all the top shelves are very interesting. Starting from that little steamer, I began to think about a 12v locomotive in 8-wide. So I started designing another small steamer (I'd say a well known prototype): the great Deutsche Bundesbahn BR-80. 8-wide is not a common scale for me - I only tried it two times in my whole life, so it was a trial and error process. I tried to use parts that could have been available in the last 80s /first 90s - during the Phase II of the Gray Era and the advent of 9v era. And here it is...it recalls me a "fat" 7727/7730, with a touch of 7810... 8-wide gives some possibility also to work with odd number of studs (boiler is 5 studs wide instead of the classic 4-wide used in standard 12v steamers). I kept the standard cylinders, the ladders, rods, red buffers and magnets, which fit nicely an keep the 12v feeling alive. I used Some SNOT for the doors, using headlight bricks. Everything was already experimented at the time (e.g. the B-model wagon with horizontal sliding doors in 7735 instructions). Right side is quite symmetrical to the left one, apart some details. 12v motor looks nice, now that the body is correctly larger. Weights can sit on top of the motor - but the model could already be sufficiently heavy to have some decent traction and pulling power. I think adding lights won't be a problem nowadays, but for sure at the time (80s/90s) it could have been an additional challenge ! But...there are some issues that must be noted: The buffers overhang is quite...massive - and this SURELY will create problems with 12v switches, since the buffers will collide with the switching electric mechanism. Coupling wagons on R40 curves could be impossible...since this BR80 is longer than any other 12v locomotive or wagon not based on bogies chassis. Weight of a complete train could be excessive for the poor 12v motors. I think it has been a very fun experiment, a real "12v+" MOC...but being realistic - in my opinion it's too limited by the motor, wheels size...and 12v track geometry itself . Maybe, with 3d printed 12v wheels and a PF-based motor it could work on PF flexible track - but it would then loose 90% of its "vintage" appeal. I'd classify it as "Virtual Shelf Queen" ! Ciao!

Hi everybody, I have been carefully watching all trains 7730 on sale in different countries since summer 2017. At the beginning, I realized that the 3 * yellow cones listed in the inventory in bricklink had axle hole: https://www.bricklink.com/catalogItemInv.asp?S=7730-1 The yellow cones 3943a: https://www.bricklink.com/v2/catalog/catalogitem.page?P=3943a&idColor=3#T=C&C=3 This yellow cone 3943a appears in two sets. 3 used for the train 7730 and 2 used in 599-1. But many trains had the other version 3943b with axle hole: https://www.bricklink.com/catalogItemIn.asp?P=3943b&in=S This version is used in two sets. One used in 4982-1 and 2 used in 6954-1. Lego produced both versions since 1979. But there are some doubts on this. Sets in which 3943a appear are produced in 1979, 1980 and 1981 (msotly). This suggests that sometime about 1981-82, Lego replaces 3943a with 3943b. The train 7730 was produced from 1979-82. Then probably, some sets made in 1982 came with 3943b. About one third of the trains i have seen have the version 3943b. As the two versions are as rare as the other, I simply conclude that Lego released some of them with 3943b. It is not likely that so many private sellers lost all the three yellow cones 3943a and then bought or found the other version 3943b and replaced with them. Thus, if you bought this train in your childhood and still have it, could you please comment which version are your yellow cones? If you still have the box, could you check if it is D/F/NL or UK/F/I version? It its also helpful if you tell from what country the train was bought. For learning about different versions of box, see: If you could attach a photo of your train, box(the language part on the right side of the front box) and cone, it would be great and helpful. Also, a photo of the bottom of the motor, if you are sure that the red motor is not switched with another one. Reading the number on the bottom of the motor, we can see in what year it is produced. Here is mine where you can read 38 0 which means week 38 year 1980: This will help me to come up with more evidence to submit a change of inventory request. Regards Here I put some the trains on sale, now or before coming with cones 3943b: https://www.ebay.co.uk/itm/202086086008?clk_rvr_id=1385696026058&rmvSB=true http://www.ebay.ca/itm/Rare-boite-Lego-TRAIN-7730-briques-neuves-jamais-jou%C3%A9/172901510590?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649 https://www.ebay.it/itm/152813017599?ul_noapp=true http://www.ebay.ca/itm/Lego-Eisenbahn-12V-12-Volt-Dampflok-G%C3%BCterzug-7730-mit-BA-OVP-komplett/263014487777?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649
