Re: SAMRA Show Jan. 27th-28th
This is a discussion and not personal. WE are all trying to understand
what is going on and to investigate options to make it easier to run and
have run.
WE used track 2 flawlessly all day on Sat. from the CAB1. On Sunday we
started it up again and all went well. Then we put a train on the track
and did everything the same as we had been doing, just like you notes but
we could not get the TIU to turn on track two. WE turned it all off and
on to see if a reboot would help but nothing. I tried for 30 minutes to
get power on. I eventually gave the newer member my track so he could
get running. The hand held said RF out of range intermittently
alternating with 22 volts track 2. I do not remember how to address
that. I eventually bypassed the TIU and again used the track. I can not
explain why it happened or what was happening. I switched controllers
and batteries but no change Still out of range.

I am still thinking that the switch would be right after the
transformer. The switch would send power to either the TIU of the TPC.
I realize that we would loose the ability of a halt command from stopping
a track on the TIU as you pointed out. This is a point that must be
considered. fortunately we have not used the halt button often but when
you need it there is nothing else that would work for a track on the TIU.
So a deviation of this idea would be to put the switch after the TPC and
have the option of going through the TIU or not. This would keep the
halt command functional. A switch would not be added after the TIU. One
side of the switch would go to the track connections and the other to
the input side of the TIU and then the out put to the track. To run on
TMCC, you would only need the CAB1 and to run on MTH, you would still
need to power up the track with the CAB1 and then the TIU. Maybe a
compromise????
I would think that another track could also be done the same way so that
we could have two tracks using the TIU if we wanted.
