RailwAI has trouble replacing some trains and has some very weird equipment choices - like three locomotives in a row for small trains even on fairly flat routes.

Hello, this is my first time to report the issue.
I've just noticed a issue on a AI on trying to build a tram network.
It seem once building a tram route it hasn't succeeded every time it did that even when installing Newgrfs with trams included.
The example as seen on the attachments below the script tells me the following issue:
No path found 
at 183469
result: false
Something went wrong while executing a plan. Undoing...
ERR_NONE
Idea could not be executed
While I'm trying to find a solution I wonder if it is a bug otherwise is there any solution I should try? Thanks for reading!
Thank you for reporting this bug. It seems RailwAI has some troubles using tramways in cities and I'll start looking into this.

Do you have a savegame for me available? From a screenshot I can't determine why the choices were made (game settings, NewGRFs, ...). For now, RailwAI doesn't take into account whether a line has a lot of slopes or not. It could be intended behaviour here: sometimes trains are assigned an extra locomotive.

I did some testing and this behavior seems to be connected to the weight multiplier for freight trains. On stock game setting it to 5 will make RailwAI happily run three locomotives and six wagons on even the flattest routes. Whatever power / weight ratio it tries to achieve, it tends to produce weird results for weaker locomotives.
