I can't locate any of the images we posted a while back when discussing memory usage in the techie forum, so here's a couple from a wee session on photon's Southwest England route, the 1W23 Waterloo-Weymouth scenario:

Immediately after loading the scenario...

When departing Waterloo...

Yes, the more memory used the greater the possibility of problems, but it can't be touted as an absolute "when you hit 3.5GB it'll crash" situation. OK, the commit charge is slightly under 3.5GB in those shots, 3.46 when departing Waterloo and a private allocation of 3.06, but they're close enough to the suggested limit to suggest that I should have been heading for a crash or at least a huge pause---neither of which happened.

Because they feature a particular trip...there are many shuttle type scenarios about though, admittedly using 'sensible' traction rather than shunters! :wink:

The duration has never been seen as a factor with regards to stability, the limits are usually thought of as being asset density so you should be OK---have you a particular route/trip in mind?
Duration is not directly affecting stability, but distance covered in a way is - and therefore a long trip over a long distance could see a crash after having covered some number of route-miles. It highly depends on how demanding the route is however.

For instance, on the route Western Lines of Scotland there's a scenario with the Flying Scotsman that, if I'm not mistaken, takes about 2.5 - 3 hours. For that route, that's no problem.

However the German route Trier to Koblenz, the Moselle Valley route, when I drive a scenario from Trier to Koblenz which will take around an hour, I'll have to save before reaching Koblenz - it will often crash when getting near to Koblenz with some sort of out-of-memory error.
This is because the route is very demanding and TS has loaded a lot already into memory, that it can't fully release.

After crashing, restarting TS and loading the scenario from the savepoint, I can usually finish it.
