Hi All

Can the Cs2 automatically increase or decrease the speed of a loco by means of aS88 ?


I have a very long stretch of straight track (more than 7 meters long) where I want to increase the speed of the loco’s
and decrease the speed again to normal cruising speed after the straight. I also want to decrease the speeds when my
loco’s are approaching a station before a braking module brings the train to a halt.

Any suggestions would greatly be appreciated.

Kind Regards
Ak

Hi Walter
Thanks for your feedback. I suspected that’s the case.
I only use Marklin’s Cs1 and Cs2 to control my layout and do not really want to go with other computer controls.
Hopefully Marklin will one day incorporate this function into the Cs2 since we can already control other loco functions via the S88.
Enjoy your digitalizing
Kind regards

This is fundamental limit in CS2/CS1 (or any other stand alone command station)

To give a command to a loco to change the speed it needs to keep track of where the loco is on the layout, so when contact A is triggered is knows this is train X.

At the moment you could give a shunting command (decrease speed to slow) to a loco when a certain contact is triggered, but then the loco will slow down regardless of where it is on the layout. Only way to control speed of loco’s is by using block controlled by K83 (power on/off) or using a more gentle approach with brake modules and soft acceleration settings in the decoder.

When I realised this fundamentally restriction I opted for fully computer control of layout.

However I don’t not see why the CS2 (being a simple Linux computer) cannot eventually have such features build in. I think there was some discussion (wishes) that new signals may have a 2 way communication and could in theory then talk to a loco and register what loco just passed the signal?

Hello Johny!

I don't have (yet) the lastest version of Märklin firmware, and like Tom said above, seems that that new update have that feature of controlling the speed (even if the CS2 did not know which Lok trigger S88).

With Rocrail, if you explicit assign a Lok to a named block, yes the software will know which Lok trigger each S88 contact.

Cheers,

Walter

...mmmmh....it is more sophisticated than that and despite I personnally haven't experienced it yet, I think that you can use several locomotives. There is a completely new function, the "teach-In function"
The new feature allows the integration of controls for the locomotive, such as orders for rolling or switching , also orders for durations .


Through the "Teach-In function", the user can prescribe scenarios that are automatically saved by the system. In addition there is a possibility of editing scenarios to complete and correct & register them manually.

For instance the shuttle route.
Until now , on a shuttle route between two stations we could only let one train moving. It was not possible to activate switches or to commute with two trains on a common route. With the last update now, just set this scenario once and for all. We can make it for two trains....
This last update looks very interesting. We can have automated roads with durations. This is a new way to establish roads if we want.
For instance: now it should be possible on the same unique road to have one signal showing two different positions...(thanks to how the system can manage durations....)

I quote myself because my English was probably wrong, I should have said " on one route (only one contact S88) it is possible that signals or turnouts can be switched twice ...".
