Before I continue working with this map, there is a big hurdle ahead that I want to plan before dealing with it. In Denmark, all long distance routes are connected somehow with trains splitting and coupling in many different places, leaving pretty much all of Denmark with a direct train to Copenhagen at some point. The problem is that they all connect to the same 2-3 hourly trains which then have different destinations throughout the day in addition to its usual destination (i.e. Copenhagen - Århus/Ålborg). See the map below, I am talking about all yellow and red lines being interconnected (disregard the one going to Sweden).

My problem has several parts:
- I have alarms turned on for missed departures from a Timing Point to catch problems early. This means I can't do gradual increase in service day by day, I have to add all trains to all lines at once (that's ~70 departures from Copenhagen and back), each with slightly different destinations and train consists.
- Some regional lines (green) are connected to the InterCity lines at night, but not during the day, further complicating matters.
- The same number of train cars have to go east and west, so all ~70 departures have to be balanced with the right number of cars at the right time
- Coupling and decoupling: How much testing is needed to make it 100% working correctly?

What I am most afraid of is having problems right when I start all the trains. How do you do it? What tips do you have? Maybe I should have fiddle yards to do partial implementations first? Or cross my fingers? Please help :?

Reading about InterCity on wikipedia in English, more detailed in Danish or the concept briefly in German.

Well, writing a post late at night doesn't make it more reading-friendly. In essence, my question is:
If you have a huge (~1000km) interconnected network of lines that can't be implemented in sections/parts but only as a whole. How do you do it?

Hello Matias,

I have not build such a hugh system with splitting up trains like you yet, but other through-coach-systems.
There I worked in tree steps.

1.) Build the main line, eg. Copenhagen - Århus/Ålborg and testing it.
2.) Build the connecting services that later will be split up e.g. Fredericia - Esbjerg, so that the passenger have to "change" the trains. Than test the network again.
3.) Install the shuntig activities between the conntecting trains so that there are "through-trains"

Hope this advices will help you.

Best regards.
Steffen

Helllo Mathias,

personally I think it is impossible to start all the trains at once, esp. if they are connected the way you described it. There are just to many occasions for errors. As you cannot surveil every detail in this large layout a major breakdown of the network is most likely. Perhaps you will have a nervous breakdown as well.

My suggestion is to build it bit by bit. Start with the trains leaving and arriving at Copenhagen - as far as I see it there are two major directions. Take one direction and commence service station by station. For the other lines just build temporary solutions, e.g. that trains can return, but don't put too much efford into them. Ignore the timing point alarms of the areas, which are not finished yet. Test the areas that are finished, and when they work properly, go to the next station.

That's a piece of work, but believe me, starting all trains at once is hardly going to work. Only a prodigy could anticipate every situation that might occur and enter the correct conditions for shunting points etc.

Good Luck and best regards,


Sebastian

Thank you both for your suggestions. I think the partial approach is the way to go, the problem is that this simulation also simulates correct train lengths in regards to time of day and the composition of trains. The key to all of this (where most splitting and coupling takes place) is Fredericia.
By doing a partial implementation I would have to have very big fiddle yards for trains to turn around with the correct train number and composition for their return journey (unless I do an 'unrealistic' partial implementation first). I hope to have some idea of what to do and try it out this coming week.

Conclusion: I make a fiddle yard north of Frederecia, but keep trains to all other parts south of it. I hope that is a good limitation.

On another note, I made the train for the line Vemb-Lemvig-Thyborøn (VLTJ or MjbaD), it's uploaded on www.jbss-bahnarchiv.de/
