| - | Trains will run on HOm/TT gauge track, since japanese railway uses 1m gauge trach which scales down to 12mm. | ||
| - | I intend to run HOj (1:80) trains, since they are available from suppliers and will not look much out of scale. | ||

Modules will be connected using Tillig bedded track endpieces like in T-Trak module system, which uses Kato Unitrack rails.

| - | I should decide which module I begin with, to start with easier landscapes. Perhaps I should make couple of intermediate modules and then Uenoshi station. This will allow running and switching operations within Couple of modules. | ||

| - | After that I'll make other stations along the way: Nishiote, Nii and Iga-Ueno. Those modules will allow to assemble long straight layout. | ||

However, while I can use flex track on main line, there are only Tillig EW3 turnouts available on the market with 984 mm radii, so I need to use those instead of 1150 mm.

| + | * Discovered, that Peco turnouts are too expensive and no available from a single store. Tillig points are most similar to Iga Line points. Tillig flex point kits are much cheaper than ready points and can be adjusted as needed. There are metallic paints that can be used to color plastic parts. Also plastic pars can be replaced with metal rail profile cut to length and bent. | ||
