  1. It's a tiny 009 layout, one or two little locos. Power districts is overkill
  2. How do you calculate the full overload current? Knowing, as you do, the equipment I'm using (NCE PowerCab, 009 locos) how to determine this? And isn't it possible to build in an overload protection?
  3. The track bus wires cannot be directly connected to the back of the PCP unless I mount the PCP directly on one of the baseboards, even then the wire size would probably be too large for the connector supplied with the PCP. I was planning on a detachable control panel (it's a portable layout) which is no problem with the EzyBus which only needs two pairs in a CAT5e cable. However, as you point out above, the PowerCab is connected through an RJ cable which I have just measured at 6.5 mm wide. There are 6 wires in it and therefore they cannot be bigger than 1.0 mm so why would I need anything heavier to connect the PCP to the track bus? My track bus will only ever carry the load for one or two 009 locos, no sound or lights, so I was hoping to get away with a smaller wire size.
  4. Ok but what would you run from the control panel to the mains cable?
  5. As I said, accessory bus is NOT DCC, it's Ezybus by MERG and uses Cat5e cables.
  6. Thanks again for the input, all useful stuff
  7. Thanks that's what I needed to know ☺️
  8. This is track bus only, no accessories. Two 4' X 2' baseboards, 009 simple layout. I'm using MERG Ezybus for accessories using Cat5e cables, can I use a Cat5e pair for the track connection?
  9. Thanks for all the replies but the original question stands. Do I have to use the heavy wire from the Power Panel to the baseboard?
  10. Everywhere I look it recommends using a wire size of at least 16/.02 for the track bus, some places twice that size. However, does that wire size need to be that big right back to the DCC power panel - I'm using an NCE starter kit with the Power Panel which has RJ45 plugs for the controller and a small PCB connector on the back for the track connections.
  11. The blades need to be bonded to their respective stock rails to get good continuity and to prevent shorts from oversized wheel flanges. Therefore you have to isolate the frog. Modern Peco points already have this done but these are old ones
  12. If I switch the frog I'll have a dead short as both blades are connected to it. The frog has to be isolated. Servos mount under the baseboard and I think I have a way to remove the spring but I will see how it works with it in place
  13. I have inherited an 009 layout which has the track already laid down. I intend to operate the points with servos and have run into a couple of snags a) I cannot remove the springs which lock the point blades, these are old points and the access to the spring is underneath. Can I leave the springs in place when using servos? b) The person who laid the track did not drill any holes for the point operation. I have tried to drill from the bottom up after drilling a tiny pilot hole through the hole in the tie bar. I have had limited success by placing a No 10 scalpel blade under the tie bar to stop the drill bit which is marked with a depth gauge of white tape. Anyone got another solution? c) The points are all electrofrog but being old the frog is electrically connected to the switch blades. I don't want to rely on blade contact with the stock rail for continuity so I'm thinking cut the blades one sleeper away from the switch blade pivot and then bond the blade to its stock rail and have a frog switch for polarity. Is this the right way to go? Thanks in advance David
