Great software for designing model railroad layouts

Railmodeller is very easy to use and has made it simple for me to lay out my new H0 scale modular layout which uses Fleischmann Profi H0 track. I use it to test various track configurations and am pleased with the layout it's enabled me to design.

I am now trying to lay out a copy of my H0 layout in Fleischmann Profi N track (with roadbed) but there seem to be some problems with the track library: elements don't align as they should. I'm hoping this can be fixed as Railmodeller is the only good Mac layout planning software I've found.

Best Bang for the Price

For years I used RR-Track to design several layouts in HO and O Scale. Got to be very well versed in all of its features and options. Got rid of my PC’s and bought a Mac. Great move but RR_Track does not offer a Mac version of there software. Sniffed around on the web and tried a few compeditors. Tried to balance price and features. Came across RailModeller, tried the FREE version and figured it was worth the price so I bought the PRO version. Took a few hours to learn some of the features but I bacame very comfortable with it and am enjoying the process of designing a new 11’ x 22’ HO layout for my basement.

Right now the main enhancement that I would like to see would be an expanded library to include maybe 10-15% of the buildings that Walthers offers. The current offerings in RailModeller is very limited.

I would recommend this software to EVERY Mac user on the planet.

Excellant Software

Building my layout with no diagram other than what was in my head, I didn’t like it when all the track was laid down and trains were running. Track and cork were glued down and unsalvageable. Ripped up and threw away 3/4 of it. Spent the next 2 month utilizing this great piece of software designing my new layout. I have tried others and wasn’t impressed as I am with RailModeller Pro and the learning curve wasn’t that bad. Started building the layout per drawing and toward the end didn’t thing it was going to fit. Boy was I wrong!!! Worked out perfect per the drawing. Only problem I have and I know it is me is understanding how to do elevations, it was frustrating at times. The author of the software responds quickly given the time difference and is highly helpful. I fully without a doubt recommend RailModeller Pro!!!
