The AI does very well by the way

And if that depot WERE on road level,trains whose orders involved the right angle turn could get stuck there.

Just bought out the latest in the game I play most actively.It had 73 stations of which 35 were unconnected,and in cases had 3 or 4 by the same industry.Also some cases of linking track to platforms the long way around.

Found another problem or two...I am playing it in a game with NARS vehicles available,which it always builds in preference to the default set...but it tends to not attach the cabooses without which NARS freight trains can't stop.Also,it's building only electric tracks while building only steam engines?

AFAIK AIs are not required to attach a caboose to the end of their trains. (handling engine/wagon compatibility is quite the nightmare anyway...) Does this really cause a problem with the AI?

Some of the trains were losing money,I found one moving at I think 1 mph after my company bought the Ai and sent it to a depot to get a caboose.I think they operate normally until they break down.

There's a slight bug: the AI builds railroads that have no vehicles.

For example, I'm using "Useless Tracks" newgrf, it has planning tracks and lifted tracks (roadbed only). The AI chooses to build planning tracks since they are cheapest. However, those track types have no vehicles, so AI just spends his money to build completely inoperable lines.

AI should check that the track set has suitable vehiles available before building.

AIs are not required to have a caboose. When Baldy buys out the AI and AI trains becomes human-owned trains, on the other hand...

Just goes to show what a bad feature those cabooses are.

And just which vehicles require brake vans?

Interesting that it builds the cheapest "Useless tracks"...it builds more expensive electrified tracks for its 1920s steam engines!

Here are more examples of bad depot placement.
FastPTPAI 4, OpenTTD 1.4.2. My company is red. I bought 50 trains, including this one, from a bankrupt FastPTPAI. This train wants to reach Kedhead Cross Mines, but can't leave the depot, because the depot has no connection to the sloped track. The industry at Kedhead Cross Mines has closed, so I am about to sell this train and demolish this station.
This is from an old game, perhaps an older FastPTPAI version. FastPTPAI is pink. There are two problems here. First, the depot has no track connection. Second, the depot is facing the wrong track! This train wants to reach Sedingwell Mines. If the depot faced the other way, the train would not be stuck there!

train can't unload coal at that station

2cc trainset has passenger-only monorail. This AI attempts to use it to move other cargo.

Excessive CPU usage in valuator function

Is this project still active? The AI looks promising, but it has big trouble when it comes to building depots.

Some routes are, well... suboptimal. However, this is a common problem for many different AIs.

In my "Which AIs are now actively maintained?" topic this one was mentioned in 2015 as not updated in the past year and a half.
The programmer's most recent post was in 2018.
