    Building 7777

    Thanks for sharing the photos of the oil depot! I tried to build this one myself, but never finished it and actually just recently took what I had built apart. I was going for accuracy and just could not see enough, especially of the platform for the yellow tanks. I like your solution though.

    Monorail 6991 Motor Help, please

    Glad to hear you are making progress! A couple other things to try: With the 3 position switch in the position the motor is now running, try flipping the 2x2 wire connection 180 degrees. This will make the motor (as witnessed by the metal gear) spin in the opposite direction. See photos for clarity. If it does, I would say the problem is most likely the switch. Perhaps you live near the ocean and dampness or salty air has corroded some of the metal in the switch. This seems plausible as with some cleaning you have restored some function to the motor. You could try sliding the switch back and forth a bunch of times quickly to wear through the corroded film on the metal and try it again. If that doesn't work I would still try the battery directly to the contacts on the motor as mentioned in my previous post if you haven't already. Just to 100% easily eliminate the wire as the problem. It's still possible there is a wire issue even though the light works on the wire. The light uses 2 upper contacts, the motor uses all 4 of the lower. Could be a short or corrosion in there affecting it. It's unlikely but it would be nice to be sure.

    Monorail 6991 Motor Help, please

    If the motor is truly dead, the easiest option is to buy a replacement on Bricklink or eBay, but these motors are very tough and i have never had one fail yet so I have personally not tried to open one. The wire between the battery box and motor can fail quite easily however. Have you checked the continuity of the wire? You can easily touch a battery directly to the motor to take the wire out of the loop. See photo below. Also, can you easily turn the metal gear on the bottom with your finger?

  4. Very interesting find! I really don't know much about Samsonite Canada, does anyone know what years they operated? During that time period were all sets sold in Canada produced by Samsonite? The paper inserts are interesting to me as well, and quite a few sets from the period had extra white paper inserts for various reasons, usually to make a correction to the instruction book, but the reason for their use in this 7710 is unique to my knowledge, although various other sets have them to show how batteries or add on motors work with a set.
  5. Hey Reza, I'm having trouble following your question exactly, but before I dig too deep, the only oddball variation with 80s train wheels I can think of is the the black wheel sets with red pins variation, I believe they are only in some 7735 sets. Mine has them anyway. Is that it?
  6. Thanks all, I thought it unlikely the older version of the track came with instructions but just wanted to make sure. The back of the box serves as the instructions, showing how to attach the track pieces together, that and the lack of any instructions for sale even though they made many thousands of these was almost proof enough for me. Does anyone have any thoughts on the boxed My Own Train 9v motor (10153)? This one I find it more likely that it had the small instruction sheet in all of them, even if it was purchased by itself. The back of the box shows set 10205, which is also shown in the instructions. The bagged 9v (5300) I believe did not come with an instruction sheet.
  7. I have never opened a new box of 9v straight (4515) or curved (4520) track. My question is, did the old style "System" version of the set come with an instruction sheet? It appears the newer version "World City" sets did, as Bricklink has photos of this in the catalog, but I can't find any reference or photos of an instruction sheet for the older version. A second similar question applies to the the My Own Train boxed version of the 9v motor (10153). Did this set always come with instructions? The instruction sheet listed on Bricklink, looks like it applies to a specific set (10205), and I'm wondering if this sheet only came along with the motor in copies of that MOT set.
  8. I am not sure how many sets I could build from memory, but this reminded me of when I was a child and had a large classic town layout. My older brothers used to challenge me by removing or moving a single LEGO piece from anywhere in the layout. I was always able to locate the problem in short order, no matter how small the part! Here's a link to a thread I started about childhood layouts that has some old photos of it.
  9. How about another type of hint? Is the variation a minor a major change? Is it due to a part change? 7740 was made for quite a few years, do they show a different type of wire for example? Maybe it was the graphic on the back page, this changed on various instructions in the late 80's for example, so maybe 7715 or 7722. Without any detail about the change, it is impossible to figure out unless someone happens to have multiple copies of the sets to scan through, or if they just happen to know the answer off the top of their head!
  10. They are both the same, 120405 Here is another error from the same instructions, the red cap was drawn twice, overlapping at different angles, a "spacial error." The was not corrected in either of my copies.
  11. Reza, here is the example of a color error in an early printing of 6392 instructions. Keep in mind, the instructions are identical otherwise, and have the same printing year (1985) The first photo has the error. In step 9 the 1x1 plate is colored red but it should be white. Notice in step 12 the correct white color is shown for the same part. In this photo, step 9 has been corrected and appears in white. I call this error a "color error" which can be found occasionally in sets from this time period. There other types of errors too, one I call a "spacial error." This error has the piece drawn in an impossible way, either floating unattached or occupying part of the same space as another part. I.E. it was drawn wrong as opposed to colored wrong. I have only seen this a couple times, but never made a note of which sets so I don't have a ready example. I know it reminded me of some of M.C. Escher's drawings with people climbing steps in multiple directions!
  12. I don't know off the top of my head which one it is, but if I had to guess, one of them had an error in one of the instruction's steps which was corrected in a second printing. This happened occasionally with Lego instructions of this era.
  13. Ahhh yes, it really does look better! There is something about the new gray with the old, they just don't go well together!.
  14. Looks fantastic! Very authentic vintage look. It looks so much better on the 4.5 track too, the PF track is offensive to my eyes.
  15. This question has been asked many times over the years, and I imagine only a handful of Lego employees from that time knew the true answer. It is probably lost to the ages. However, I do have a guess, but it is only that. I think Gary is right, it probably had little to do with the voltage system, or child safety laws as this rumor seems to persist. I think rather that the answer starts with fact that in the US we have very few passenger trains. Compared to Europe with it's vast network of rail service, the US has a few commuter routes in some of the bigger cities and even fewer interstate routes. The distances between US cities is so great that with the dawn of air travel in the early 1900's, the sun set on passenger rail service. Therefore, kids growing up in the US in the 80's had much less appreciation for trains than in Europe and other parts of the world. I know, I was one of them... You see where this is going, and Lego did too. Is there a big enough market in the US to roll out the 12v system? Apparently they decided no. Keep in mind, that the 12v system is much more complex than any other Lego theme. A parent can hardly buy one set for their child, they need track, and switches, and signals, and controllers and so on. A pretty serious financial commitment on the part of parents. Oh and all those sets take up a lot of precious retail shelf space too! So maybe Lego decided to roll out the 4.5v and see how it went? I don't remember even seeing 4.5v in stores, TRU at best? I'm pretty sure all of mine came from Shop@Home. Only 7722 even came in a US marked box. Maybe the trains did a little better than they thought, but at that point 12v was winding down, and so they rolled out all the 9v sets to the US? Unless we get a visit from a retired Lego manager, we will probably never know the real answer, but it is fun to think about!
