 | | Isolating rails —Jonathan Reynolds
|
| | | Has anyone tried making isolating rails? By this I mean a purposely modified section of track with a cut in one or both rails (can be done with a modelling grinder etc.). All the postings I have read refer to using 1 stud gaps between the rail ends (...) (25 years ago, 5-May-00, to lugnet.trains)

You can read more about it on my webpage: (URL) have also been thinking about isolating two stretches to use different powersupplies in one layout. I'm a little puzzled how to do it, (...)

The motor may stall if you have the 2 power supplies giving opposite polarities of near the same voltage, (...) (25 years ago, 6-May-00, to lugnet.trains)

Mindstorms has more than 2 voltage outputs (8+, you can write a program to split it in NQC to 100 discrete power levels, from 0.01 sec power on to 1. sec power on) I have a fair amount of experence doing exactly what you are proposing to do, (...)

| | | | (...) Yes, It is possible to cut trough the metal strip only (well, almost only), on de spots where there are gaps in the plastic supporting these strips. I've done this using a mini tool with a thin cutting disk. It makes a very smooth cut, thin (...) (25 years ago, 10-May-00, to lugnet.trains)
