My expierience with big locos

[Schraddel]

Now intensive test runnings were made:


On the layout easy runing onto the main.





On the other end of my switching layout.
But wait a little bit, there is a Atlas Customline Code83 #4 switch in the foreground.





Later the spacing between loco and tender will be closed by an diaphragm. These are the movements a diaphragm will have to cope with.





So it looks alike when running over a #4 switch. That is a extreme value for the L-105 Challenger, but it negotiated it.







A Peco Streamline US Code 83 #6. Much easier to negotiate.







A Peco Streamline US Code 83 #8.










Negotiating the vertical kurves from main to industrial tracks. The loco tackles it too.





Here was the very end. These Challengers are not made for switching in tight eastern industrial areas.
I resume the D&RGW L-105 Challenger sucessfully completed the test running. The 1300g weight of the loco forces the rather stiff springs to work really. The loco floats rights on it's spring suspension and there is really springing action. The tender has it's own weight of ca. 200g, so the complete loco with tender tips the sum weight of 1500g (app. 53oz) on the kitchen scale.
But this is not the end, there is much of work still to do.
