ok nobby let me see if i can confuse more
the 5091 is a motor-it needs power-the power needs to be controlled via a wich box-ie the EPL
otherwise the power is on, and you have no way to reverse the power and thro the 5091 the other way
so yes the 5091 motor (and internall switch) needs a momentary contact switch to shoot it power either one polairty or in reverse polarity
unless of course you skip the power and use your hand manually
heres the deal
first
the 5091 is a motor, which changes the signal lights AND changes a switch inside-
this switch is a single pole throw-simply stated, its an on/off-it either turns on or of the isolated section between the 1015u sections
second
the lights have thier own power source, as i mentioned above -they light even if no powere goes to the 5091 motor-
third
you can indeed not use the 5075 switch box, and simply slide the black plastic bit below the light mast manually (if you chose or had to) this slide will not only change the lights, but move the internal on-off siwtch
fourth and finally-the isolation sections are nothing more than "jumpers" ie theres a break in the rail
under the little plastic top with a screw bit in between the sleepers are electric posts-these are used to run wires
they connect the mainline track power on the isolated rail-to the 5091, and then frm teh 5091 back to the inside rail section of the 1015s-simply they cut or connect power to the isolated section by making a break , which the 5091 controls
go to the diagram link with the picture above- its above that which is pictured in this post
as i recall -from memory several years ago-the 1015s use the 2 inner most-center posts-ie one on either side to the center to connect-use the picture and mimic it-one set of posts links the OUTSIDE rails (outside the isolated section-ie so the track power from one outside section connects to the other outside section-so one set of posts simply jumpers this part -the outside jumper will need a long section of wire, which you can run under or along side the two 1015 sections-this wire is carrying powere from one outside ('outside' meaning outside the isolated section ) mainline to the other outside mainline
the other set of posts jumpers the INSIDE isolated section (in between the rail gap-this jumper goes through the off on switch in the 5091-when its in the OFF position, the lamp is red-the train stops because there is not power to one rail
change to green, the inside isolated rail gets power and the train goes-
the section needs to be a bit longer than your lngest loco-and-the loco musnt be connected to traling cars that pick up power-say for lights-from the track AND WHICH are connected to the loco-ie like the small , two wire coach lighting wires , which act as jumpers -or-the lamps which plug into the back of the loco IF those lamps also go to a car with wheels that also pick up track power-
(in this case the train coach lighting wires would then act as a jumper cable trailing outside the isolated section because the trailing part of the train, outside the isolated section (isolated section is unpowered-) picks up power from the track and carries it to the loco (and the isolated section) via the lighting wires
clear as mud???

So, I have got a 51120 'signal shed'. The plan here is that if the orginal controller is only set at half-speed, then he can use the 51120, but the speed of the train will be limited. Will it work? I dunno, but I think it will.
