From parts list to hobby shop
Trackplanner doesn't sell track. When your plan is done, the parts list shows every piece with its part number, and the app suggests retailers where you can buy them. In the United States these are:
- Amazon.com
- Factory Direct Hobbies
- Kato USA
- Micro-Mark
- Model Train Stuff
- Plaza Japan
- Trainz
- Walthers
- Yankee Dabbler
In Canada: Amazon.ca, Credit Valley Railway, Oakville Model Trains Depot, Otter Valley Railroad, Plaza Japan and Trainz.
Inches, feet and Letter paper
Set the unit to inches and the app shows lengths and radii in inches, track totals in feet and areas in square feet. Printouts can use Letter paper.
