One problem i have with Eskalon is keeping the stock coupled together! The problem is a design flaw with the otherwise excellent Liliput diesel locomotives of which i now have 2. The NEM socket is a fraction too far back so a NEM coupling with a hook (NEM 360 is it?) can't be used as the hook cannot lift high enough to allow for the other stock to couple properly. Its just a matter of a millimetre or so alas!
That means i have had to use the non-hooked coupler that comes with the locomotive. Thats fine to an extent, and that extent is when the track isn't level or a bit bumpy as Eskalon is at parts of its main loop. The stock becomes uncoupled from the locomotive. If both loco and stock could loop each other's hook then we'd be fine but as above thats impossible.
I'm now trying Kadee couplings (which came with the loco) and these seem to work. One problem i have though is that my new equipment van has a non-interchangable coupling so its stuck with the loop and hook method. My open wagon is thus acting as a match wagon with a different coupler at each end.
As for the passenger train well the only way i managed to get that to work in push mode was to use the flat semi-permanent coupler. This reduces flexibility of course as the only way to uncouple the loco from the train is to physically lift it from the track but with 2 mainline locomotives now thats not so much of an issue.
We'll try the Kadees for now, i probably need another wagon with interchangeable NEM sockets so i can top and tail any stock like the van which cannot use the Kadees.
