Scale
Does OpenTTD really have a ‘scale’? Perhaps but it’s a little inconsistent here and there. I think its hard to have a conversation about time for scheduling without acknowledging distance and speed.
I can’t remember exactly how I got here but for me, each tile is
50m x 50m. It kind of makes sense as the more traditional newgrf 2 car trains typically fit on 1 tile (2x 25m carriages). You do have to ignore a few things like distance between tracks!
When you do the maths on distance between stops, it just feels right.
- Bus stops every 400m are 8 tiles apart
- Subway stations every 1km = 20 tiles
- 100km = 2000 tiles
- 512 x 512 map is 25.6km x 25.6km
- 8192 tiles is 409.6km (near enough the straight line distance between Paris and Amsterdam!)
For a simple calculation:
- Kms = tiles multiplied by 0.05
- Tiles = kms divided by 0.05
But how does this relate to timetabling?
I used this base number to set ticks per minute based on how many ticks it takes a vehicle travelling at 60 km/h to cover 20 tiles (1km)… 1km at 60km/h should take exactly 1 minute. In this case…
690 ticks = 1 minute.

This might be quite a long time for gameplay but it is ‘accurate’. Hope this might be useful!
