What's your backup, if one of those point motors fail at 11am on a Saturday morning of the exhibition.
That's always at the back of my mind when planning/building a exhibition layout, which is why i always use manual point control, bike spoke, WIT ETC, which isn't a 100% reliable, but i've only had one failure, in all the years of exhibiting and it was a 5 min fix, KISS.
Just asking!!!!
