Some background-1.) I am on release level 5.0 which I perceived corrected Lash-up problems, 2.) independently the two engines run as advertised, 3.) I am a frequent user of the Lash-up feature, deploying same successfully more than 50 times during the past 3 years or so.
Now for the problems, I get a mix of light configurations, example, sometimes the head end engine will have the three head lights on the front lite and on the rear one red light is lite and the tail engine is dark (I believe that this is the intended configuration for the direction of travel), sometimes both engines are dark, sometimes, while moving in the forward direction, the tail engine's three head lights are lite and a rear lite is red and the head -end engine is dark, sometimes both engines will have the three front lights lite and one rear lite red. Sometimes on start-up only the tail engine will come-up, the head engine does not start-up.
I would like to hear from someone who is running a lash-up of these engines.
