you could try increasing the swap partition (UN*X) / paging file (NT) size. This will prevent memory allocation failures. however, this is bought at the price of a severe performance penalty – in particular if the device hosting the swap / paging file is a mechanical HDD and not a SSD drive.
as for the question whether or not there is a memory leak present, it would have to be investigated how memory consumption evolves during a certain period of time. a tool that would come in quite handy to do this in a graphical way would be sysinternals process explorer. however, it is true that increasing memory consumption may very well be caused e.g. by the increasing amount of population / vehicules, etc.
so to somewhat harden the evidence there is a memory leakage, you might e.g. try to run a game session for some time (monitoring memory consumption. then re-loading the same save-game you started with and comparing memory consumption (preferrably, this ought to be repeated several times).

this has cost me some frustrating hours as well.
also, especially when it comes to non-trivial track layouts, it would be _very_ appreciated if there were some means of debugging why a given train won’t the h*ll use a certain path (something like colouring tracks ahead of the running train in green up to the point where it cannot continue, preferrably with an explanation why that is so)
process explorer is a more sophisticated variant of task mgr if you will. it can be retrieved from http://technet.microsoft.com/de-de/sysinternals/bb896653.aspx
in this case, the main advantage of pe above tasm mgr is the feature that pe displays processes in a tree structure (thus grouping child and sibling processes). also, it allows to find out additional process properties (such as a process being suspended) – and alter them.
cheers
@Badajoz: when the application hangs on my machine, the application’s main (and sole) process gets suspended (at least according to processexplorer). After some ~20 seconds, a parallel process is started (windows trouble reporting stuff). This process is spawned in cases where other processes become irresponsive (they do not have to crash). If you run process explorer in parallel to train fever, and investigate the process list closely, you will probably see what I describe. Terminating the parallel trouble shooting process and resuming train fever’s main process and then bringing back train fever to foreground fixed the described issue for me most of the time.
could you try disabling soundtrack output? This fixed the problem on my machine (freezes seemed to happen when tracks were changed). Also, using sysinternals’ process explorer (procexp), it helps on my machine to terminate the error reporting process that is spawned beside the train fever process and then resume trainfever.exe.
you are correct: I did lay the tracks in one part. But I actually do not see why this should make any difference when it comes to modifying them.
I might have found a hint as to from what the freezes on my machine were caused. Apparently, freezes took place when the soundtrack track was changed. This may or may not be correlated to the fact that I was running another application in parallel producing sound output (namely Winamp). After disabling sound output by pausing the sound track player and setting volume to 0, I did no longer experience the minute-long freezes (there still occur brief stutters as described in other forum posts, though).
So maybe audio output is sth you should have a look into. My audio setup is rather uncommon, admittedly: I am using a Asus Xonar DX sound card along with a DolbyDigital-Live encoder.
Cheers,
Christianforgot to add that I’m willing (and I hope capable) to perform additional analysis on my machine and provide the results for err analysis if that helps. Maybe a memory dump of a process in hanging state would help?

ChristianHi mikael,
this behaviour occurred in new games (I tried both large and medium-sized maps). I actually never player a given game for more than ~1h (in summary). The first time this occurred, I was in the middle of completing the tutorial explaining how to establish a bus line. After that, the same game froze whilst playing through the second tutorial.
BTW: I also noticed a significant drop in allocated memory for the game’s process when the last freeze happened (down to some ~20MiB – before that it was more in the region of ~200..300 MiB). There were 10+ GiB of free mem at all times and all of my 4/8 cpu cores were pretty much idling (the game’s process itself did also not consume any cpu time according to Task Mgr while the game was frozen – I can see this w/o minimizing the application, since I have Task Mgr opened on another monitor most of the time..)
Cheers,
Christian
