Electric train load problem

[jklamo]

I have TTD patch 28 under WinXP and I have that problem:
After invention of electric trains i build electric station, depot and new train with electric locomotive and wagons. I send train to station with Full load option. Train wait and when cargo appear in station train leave station complete empty. Only way to full wagons is to send train back to depot, remove electric locomotive with diesel, then send it back to station and load some cargo, then back to depot and replace diesel loco with electric. This way train with eletric loco load fully, transport cargo to another station, but when unload cargo completly in another station, it cannot load anything again. Diesel loco works normally on same line.
Where can be problem?

try change freighttrains to off it makes train stop loading if it may be too heavy to travel

I think it's a problem with the passenger carrying capabilities of certain electric engines. I can't remember the switch, but it defaults to cause the full load condition to be reached when any type of cargo is fully loaded to capacity.

Hmmm, Train 55 works fine here.
(I assume that's what you're talking about as that's where the save is centred)

Actually me and my brother has the same problem with the latest patch and the latest DB-set. It starts to happen around 1970 (or whenever BR-103 gets available) with the BR103 and then it's escalating and finally it applies to almost all electrical locos, except those that was built prior to this year, they function as normal.
