Buckeye_Type_E strength edit?
Posted: Wed Apr 28, 2021 9:46 pm
Hi all,
This may be more of an RWA question (but I don't have an account there, so asking here first).
Like many people, I've had recurring issues with couplers separating on US routes such as Sherman Hill and Norfolk & Southern Coal District.
From what I can tell, these events always seem to involve the buckeye_type_e_coupling. Its .bin is fairly short, and includes a Strength entry, as well as a MaxForce (although the latter appears immediately after the SpringCoefficient and Damping entries).
In an attempt to prevent the broken couplings (which aren't a result of poor train handling; they usually seem to happen when I've been running under constant power for some time, and posts in other forums report similarly) I've extracted the file from Sherman Hill and edited the Strength line to add another zero, from 1000 to 10000. A repeat run this evening, however, broke a coupling again (after 55 minutes!).
Does anyone know whether Strength is the line to edit; and if so, how high it needs to be? I presume this is a numerical issue in the physics calculations causing occasional spikes in force and exceeding the maximum load - but how high can these spikes get?
Thanks!
