Hi all!!
I received a phone call from a MRR dealer in Miami this morning that my MTH UP GP35 3 Rail was in!! A few moments later a friend who also ordered one called me and said "let's go get them"!!!
I will probably have more to say after playing around for a while but here are my initial impression:
The enclosed manual sucks!! Tells you basically nothing …
They direct you to go to the MTH website, do a product search to find your product, go to the product page and download the specific manual. THERE ARE NO MANUALS FOR PROTSOUND 3E+ LOCOS!!!! I eventually downloaded a manual for the 2 rail version. Of course, this manual says nothing about the 3 rail version.
The first thing I checked was to see if there was continuity between the wheels on opposite sides of the loco. There is … good …
They say there is a switch to choose between the DCS (MTH protocol) and DCC protocols. They say it won’t harm anything if the switch is in the wrong position, it just won’t run. And it is not clear which way the switch needs to be for DCS or DCC. So I put it on the track and turn on my CS2. I get a low “buzzing” sound from the loco and then my CS2 detects a short … not good … so I move the switch to the other position and turn the CS 2 on again … no “buzzing” from the loco … so far so good …
I then defined the loco manually as a Marklin Motorola loco in the CS2. Factory default is address 3. Lo and behold, the loco runs … but only four functions are listed … F3 appears to turn sound on …
The loco takes R1 curves well … quiet running … nice running sounds ...
So I then decided to run the loco as a DCC loco … the CS2 wouldn’t let me change the protocol, so I had to delete the loco and start over again. After re-entering the loco I then tried to run it … nothing … fortunately I remembered I may have turned off DCC on the CS2 in the past, so I found the screen that does that and put the CS2 in “Auto”. I turned the speed control and it took off … I think that 12 functions showed up. F3 turned the sound on … it runs well even at slow speeds. I believe there are 28 functions available.
Here are some photos:





I forgot to take a photo from the bottom showing the sliders. I will post one later in an update.
This loco lists for US$300 and I bought it for US$240, so far, I believe it is a very good deal.
I did not try to run the loco as a mfx loco. I had it connected for a few moments and the mfx logo never showed up. Nowhere in MTH literature did they use the mfx trademark, so I assume mfx won’t function, but I will try it later and see. I really don't believe it is mfx compatible.
I will have to read through the manual a bit more. I believe that through the CVs for the loco I can change what the function buttons do. I’ll have a video on YouTube in the next day or two. I will also add any more impressions.
That’s it for now … it is getting late and I need to get something for dinner ...
