I was sent a link to a You Tube video that shows how to install an Electric Railroad Co (Lionel) control and sound board into a steam engine. It was done by Legacy Station, located near Atlanta. I am not associated with Legacy Station, in fact I have never heard of them until I was sent this video.
Anyway, I have recently installed these ERR boards into my MTH Hiawatha 4-6-4 that had PS1. It was the first engine I bought as I moved into O gauge, and I was REALLY disappointed not only in the toy like sound, but the lack of speed control. I was ready to dump that engine, but decided to try installing ERR's system. The engine is 120% better, both in control speeds and sound. It is now one of my pride an joys that I show off. The sound is fantastic and speed control, well it moves at the same rate of speed going up a grade as it does coming down, I love it.
It took me a while to figure out the install, but the instruction manual made it easy. However, I wish I had known about the video earlier. It would have gone faster.
So if anyone out there is interested in upgrading your engines using ERR control and sound boards, I recommend looking this video. It makes installation a lot easier, especially those of us that do not like to read manuals!

Now to tackle my MTH F7 with PS1 (was going to sell it!) and a KLine F7 as well. Maybe even redo my MTH 0-8-0 with PS2.
