JHF,
Just moving into our place a couple months ago I have not been able to spend much time running, most of the time is spent building and making changes we wanted to the house.
I did get time to spend about an hour or so in the Train Room. Marty E just upgraded my DCS TIU's and HHRC's to the 6.1 level so I ran some Trains today. What a difference the 6.1 makes. Everything now runs perfectly!
