I have N scale, which is irrelevant for this question. I am redoing the entire top level of my 4x6 layout. It is (was) the Atlas N-18 layout which a useless and tight double figure 8. Now the question- It looks to me that one or two reverse loops on a layout permits a lot more variety for operations and routing. Otherwise, trains will go in only one direction. How come very many layout diagrams printed in the magazines do NOT include at least one reverse loop?
It has to do with operating styles changing toward what some people espouse as prototype. Linear designs where trains travel to places and then come back as opposed to making laps. etc. Lots of layouts now have staging for keeping all those made up trains in. Running trains around loops and reverse loops isn't so fashionable anymore, but don't let that stop you if it's what makes you happy. I always include atleast a continuous run for those times when I want to railfan my layout. Seems to me you can do a lot on a 4x6 in N.
Mark: Most folks don't like to incorporate reverse loops on their layouts because of the wiring involved. With DCC, reverse loops aren't a wiring problem and in fact are quite easy; two wires in and two wires outside the reverse loop connected to a reverse loop module. The JJJ&E has four reverse loops which makes operations quite interesting. Stay cool and run steam.... [ 19. November 2004, 02:27: Message edited by: Powersteamguy1790 ]
I am going to try to design in two on the upper level as soon as I figure out how to move and incorporate my double viaduct that has to be ripped out and moved AND figure out how to use the Atlas RTS program.
I have 3 reverse loops on my layout. I wouldn't have considered it without also having DCC. I used the Tony's Train Exchange reverse loop controllers for 2 of them and the new Digitrax controller for the other. I much prefer the Tony's units. David
