Most likely, PS/3 locomotives should have the same speed profile for conventional operation. Also, there is a little "slop" in the speed control for conventional running as it's keyed on track voltage.
Simple test to see if it will be a problem, run them a foot apart around a few times and see if they run close to the same speeds. A variance of a couple percent is not significant, but if one is considerably faster than the other, it could be a problem.
I used to double head my old HO ATSF diesels (a Life Like GP38-2 and Bachmann GP40) all the time. They worked very well together. Of course, that was using DC power. In other words, it is possible to lash up O-Scale conventional locos and make them run together.
I use to run 2 conventional locomotives (not MTH) together. The engines were the same brand and model and ran at about the same speed as John notes above. I found what was more important than the engine was the track. If you have your track wired conventionally and stop on a dead spot, when the engine gets power again, this could cause one of the engines to cycle out of forward and it would then have to be reset. Not a deal-breaker as its fairly easy to fix the dead spot.
Andrew, thanks for the feedback. I agree the engines should run at the same speed, but it seems they wouldn’t run so well if there was a broken wire. I’m also reluctant to remove the shell because it’s such a narrow engine. It’s easy to pinch a wire putting the shell back on, causing a short and frying the board. Don’t ask me how I know!
I run Williams By Bachmann as well as MTH Proto 1 in lash ups all the time but not together. In case of a power interruption the reverse units will reset to the same direction in a few seconds. The old lionel e units have to be locked into the desired direction of the locomotive.
Andrew, appreciate your thoughts, but I'm going to heed the advice of the old adage, "if it ain't broke, don't fix it"! Both GP7's run well, so lashing them up isn't a priority for me. I'll risk removing the shell only if I have a more serious problem. Thanks.
I've run 4 proto 1s in a lash up. 2weeks ago by accident I ran a proto 2- 6 axle and a lionel tmcc 6 axle in a lash up,conventional. Williams I've run 3.Usually I run as was said separately to ck spd,then do it.
