perhaps "strange" from those other operators' points of view, but I'm guessing for familiarity reasons (to make it more consistent with all the other non-PRM modded TfW 142s/143s/150s/153s having blinds) though as supposedly the 153s will be getting PRM modded the LED displays will have to be refitted as part of that work. Maybe the Canton guys didn't know how to reprogram the electronic destination controller as I'm guessing its a standalone device, whereas the 175 PIS and the TrainFX system on the TfW 158s and their PRM modded 150s is all loaded with the same data...
