OpenTTD Loading & Unloading times

Question

I'm trying to calculate the time for a train to load at a station.

This website states that a full load and unload cycle takes (capacity * 2 / load_amount) days

So a full load would be (capacity / load_amount)

It also states that a "load amount" is loaded in these times:

• Trains: 40 ticks
• RV: 20 ticks
• Ships: 10 ticks
• Aircraft: 20 ticks

Using these formulas, for a monorail train with 108 passenger carriages (5076 passengers) and 10 mail carriages (370 bags of mail), it would take 5446/40 days = 136 days.

(Note: The train is on a station length 64, and the train is length 60)

However, the train actually only takes around 10 days to fully load, very different to the calculated value.

So my overall question: What is the correct formula to use to calculate load times?

Answer 1

You're mis-interpreting "load amount".

load_amount is an internal attribute of a wagon or vehicle that determines how big a chunk of cargo is loaded during each cycle. For example, a train wagon with a load_amount of 16 will load 16 units of cargo every 40 ticks. If the wagon has a capacity of 40 units, it'll take 100 ticks to fully load.

If a train fully fits into a station, each wagon will load independently, so the total loading time will be the loading time of the slowest wagon in the train.
