Hi, I use another mod "Napu's Mod" it adds in it's own tiers of trains, but they lack the grid feature or survivability I like in this mod. I asked the mod Author if he'd be able to add support for your mod, but he thinks it'd be better if you added the "injection" on your end. I was reaching out in hopes of getting your feed back.

Here's the convo for reference. https://mods.factorio.com/mod/NapusMod/discussion/67518dc33901bd4bac684709

Thank you for your time ^-^

NVM I found a mod that just adds grids to things.

Will not implement. It is out of scope of this mod.
It is good that you found out another mod to do so.

P.S.: At the time of 0.16, the only thing that has a grid is the personal power armours. So applying grids on tanks and trains was a rather new concept at that time.
But with vanilla 1.0 Spidertron and 2.0 Tank with grids rolling out, it should be very easy for modders to learn this and to apply grids to their own vehicles. It is just addition with one line of code, if don't mind sharing the same grid size and allowed set of equipment as vanilla power armor or vehicles.
