Do i always need a m84 to
stop a train or is there a
another way?

Ok Thanks
Not sure i know how the trains would stop if im
Just using cs3

Hi

The CS3 needs to know "When" , so it needs to have S88s (60881) and one Link 88 (60883) if you have a CS3 (60226)
The CS3 does not keep track of where is each loco, so for more than 2 or 3 locos, it needs the help of a train software like Rocrail, etc.

Before using Rocrail, I had a CS2 and tried using braking modules and the net result is:
- costly (you need one of those for every signal)
- heavy wiring (instead of one isolated section per signal you have 3)
- difficult to use in bi-directional blocks

After using Rocrail:
- no more stop sections
- no more brake modules
- no more signals unless needed for cosmetics
- any train can run reverse (loco pushing the train) and still stop at the right place (no need for an additional slider, slider inverter relay, conducting couplers
- any train slows down gently and starts smoothly even in hidden stations / in absence of signals

I suppose iTrain, TC and others have similar advantages.
