Thanks to you as well Loco Bill! Your encouragement and insight are very valuable to all on this forum!

Thanks Greg! I ordered some weights (4oz each) for my boxcars to place over each axel. I think you are spot on regarding your previous suggestion. I really appreciate the input from this forum.

Hi Ya'll! I wanted to share the progress of my elevated train. My concept was to have a layout that appears to be "floating". The track portion is complete, and I have had numerous successful loops without incident. Now I am only running the locomotive and tender because I have not yet purchased a sufficient power supply and am using the Bachmann controller that came with my Cow Catcher train set. The first two links are photos, first one shows the 3-degree pitch on the straights that keep the train leaning towards the wall. The track transitions into the curve to flat then back to 3-degrees, etc. The second photo shows a wide angle of the elevated track. The third link is just a short video of one loop around. Next step is power supply, adding cars (weighted as suggested by Greg Elmassian) followed by scenery (corners will have little scenes, straights bushes, trees, etc. and some scenic backdrops) Anyway, that's my vision so far, just wanted to share! Please let me know if links don't work

Yes sir, opposite ends. Thanks!

Hi Ya'll! Is it not advisable to run two separate trains on the same track at the same time? (they would be opposite of each other while running) If it's ok, Loco Bill, is the transformer you recommended powerful enough to accommodate? Just curious. Thanks!

Hi Ya'll! So in between waiting for supply deliveries for my elevated train project, I wanted to share a video I made. If you decide to watch, you'll see immediately that I am no videographer! Although the plastic logs on the log car are decent, I wanted something a little more organic in appearance without using actual sticks. In searching around the internet, I found some homemade ones, but still not to my liking. Started messing around with different techniques, this is what I came up with. As far as my research took me, I found no other similar method. I do not ever want to take credit for someone else's work. Again, I am a novice, and this Forum could be filled with methods like this. This isn't one of those commercial laden, subscribe, etc. YouTube videos, it's actually the first time I have ever done anything like this, so be gentle!

Hi Ya'll! Was there ever a version of Bachmann Big Haulers L 2-4-2 Steam Locomotives that were made to look weathered and rusty, or is the one I am looking at actually weathered and rusty? Ha, ha! It is a private listing not Ebay and says it is new. Thanks!

Thanks Bill! I was certain if anyone had a photo it would be you.

Thanks Mike! Yes, Ebay and already in process. Pity, I like the set

Hi Ya'll! We all know how well packaged Bachmann Big Haulers Train Sets are now, but how about 1992? Specifically inquiring about the Big Haulers Golden Spike. I have been extensively searching for a photo of the packaging from that time with zero results. I bought one in an auction as ("Brand New, Never Opened, Never Used, No Damage) quite the contrary. Was shipped in the original box, box no indication of damage.Shows extensive use (wheel wear and scoring),box opened numerouse times and enough damage to render it inoperable. Had a half piece of thin clear plastic covering engine and tender, boxcar and caboose uncovered inside of box. I photo documentd every detail. Just trying to add as much documentation as possible to insure full purchase price refund. Any help greatly appreciated. Thanks!

Thanks to you all! Your input and advice is most welcome and valuable especially to us novice train enthusiasts!

Hi Bill! Reason is I am working on an experimental suspended track system and even though I am designing it to be strong, I would like to keep the weight down to help accommodate speed, additional cars, scenery etc. Remember, I am a novice at model railroading but was a prototype model maker for 42 years(retired), so my mind tends to drift to the seemingly impossible, to the probable, to the doable and done.   Thanks for the recommendations, I will definitely look into them all!

Thank you as well Greg Elmassian! I appreciate the picture, I didn't even know there were Lil' Big Haulers!

Hi Ya'll! Anybody have any Idea what the lightest (weight) Bachmann locomotive/tender is? My Cow Catcher locomotive/tender weighs in over 7 pounds. If you know, I appreciate the feedback. Thanks!

Hi y'all! As a new G scale train enthusiast I decided trains around the tree at Christmas time just isn't going to cut it. Since then I have been planning an elevated track for my office. My set is The Cow Catcher with an additional livestock car and a log car. I will have 40 feet of track. My question is what transformer will be adequate to power this layout? Model and number would be most appreciated. Thanks!
