TT model railway – why are there accidents here?
Hello! I got a railway track and have been playing with it for a few years now. I'm currently working on the layout and how to improve it (I'm a beginner and have no experience). I have a section on my track where, with a certain combination of trailers, accidents, uncouplings, and derailments regularly occur, regardless of the speed.
My DB Regio (BR182 with two double-decker carriages) always decouples between the first and second carriages, but even small carriages tend to get knocked out here, e.g. the Taurus (BR182) with a baggage car (Donnerbüchse) and three refrigerator cars (was a test train), which also decoupled between the first and second carriages and derailed… :c
Can anyone help me find the cause?
Directly behind the tunnel portal is a switch that is almost always set to straight ahead. Before the curve, the track was straight ahead for about 30 cm. The accident site begins at the point shown in the picture and continues until just beyond the portal. Once the train has cleared this section, accidents are very rare.
Often, the switch is the final straw in the accident, but not always. The tunnel itself runs straight ahead for at least one meter; theoretically, I could install the switch backwards. How far would the distance between the tunnel portal (or its curve) and the switch be?
Thank you very much! 😀

It may be due to how these tracks were fixed. (screws and washers, which sometimes extend to the rail edge). Here it may be that the track disease or also the coupling bows apply. I would remove the screws and gently nail or glue the tracks. Otherwise simply go over with the finger whether there are any unevenness or lateral distortions on the rail taps. These must then be directed.
Thank you.
In fact, there is a small unevenness, which unfortunately exists in many places of the tracks. They are always on the connecting pieces between the individual rails, especially in the case of switches. How could I fix it?
They usually only lead to accidents when there are lateral shifts. They’re not so bad. Maybe carefully bend with a small pliers or align with a small hammer.
Thanks for the star. :
Well, my track is very…
Thank you. 😀
The images are static and there is no train to see. A short video could be more revealing. However, you can roll the critical area with only 1 individual wheel set and observe exactly how exactly it can be rolled through the accident-prone area. Here, please consider exactly the distance between the rails. If necessary, after the reconstruction a rail is slightly bent from the track or a rail connector is emptied and can be directed or perhaps replaced. In most cases it is quite small causes with then greater effect. The whole thing resembles meticulous dedective work. I think you’ll find the mistake. I’m pushing the thumbs.
Thank you.
I think I’ve found the mistake, yet I don’t understand why this is (see supplement)… But it works.
Hello Talbor
Nothing can be seen on the photo.
Take a train without a locomotive and pull it slowly by hand over this track section. You should then remember where there are problems
Greetings HobbyTfz
Check whether all clutches are at the same height and whether the clutches can easily move to the right and left without cornering
Thank you. 😀
Yeah, that was with most of the trains, that was a problem. However, I do not understand why the BR151 could handle it better than the BR182, although the train was not really involved at this point.
I’m sorry, I didn’t get a better picture. Unfortunately, I do not know which details I should pay attention to.
I actually found the fault – it was on the locomotive or on the clutch. But I don’t understand it so much…
