My new layout big loops 9.25 update.

Sounds like a good idea. Tehachapi Loop is really interesting to watch the trains travel up and down it. As far as your model goes, just be absolutely certain you can reach everything. Everything should be within 30 in of reach. That may require you to cut access holes to reach tough. Do not make the mistake of climbing up on top of your layout. It is inconvenient and will eventually destroy scenery.

Exactly, fortunately I have a long reach and only will need 2 access points inside loop.

4 1/2  minute loop on test run.  Flat track loop is 2 1/2 minute loop.

Running test trains today.  

I'm glad I just found your new topic on your layout construction build!!!  This is what a number of folks suggested to me to give updates on the "What did you do on your layout today" topic, plus have my own topic to make it easier for anyone to follow along my progress.  

Looks like trains can run well.  What are the overall dimensions of the layout?  So I think I got it, it looks to me like there are two loops, one is the Tehachapi that runs over and under.  The other is the flat blue line Chicago Loop.  I'm looking forward to following along!

Lookin' good - keep up the great work.

Nice.  Size of the layout (i.e., dimensions)?

That looks neat!  You don't often see that type of track plan in O-scale.  Thanks for sharing.

24'x12' main table with a 6,5'x13 leg. thx everyone.  I have run all my power to points every 10'-12' of track.  Next step is to smooth out track then landscaping.

That’s a nice big space!!

3/4 way done finalizing big loop.

Double heading engines pulling 41 box car train, couplers tend to fail or to much weight towards back, tried helper engine, jury's out on that.

Heres a couple of videos

That's a lot of cars you are pulling!!!

41 box cars plus caboose is over 31 pounds of weight, 38 feet in length.

Yep nice and slow over and under got it all.  the Silver Bullet and KCS Passenger will be underground inside the loop.
