3D model description

This is a modernized version of my previously launched "Diesel-01" locomotive. It has a new ("ERS") coupling system - optimized for most demanding track curvatures of ERS tracks and other popular systems.
Also the wheels have been redesigned to provide quicker assembly (with no external components to gather) and more stable traction.
Thanks to the modifications, this model is now a complete set of parts - even a wheel axles are 3D printed (1.75mm filament pieces are used for hinges' axles).

To learn about the assembly please take a look at this PDF instruction:

The locomotive is compatible with other popular tracks (adequate distance between gauge lines) and its native tracks standard: "Euroreprap Railroad System" (free inter-connector track model is available).
No support is needed during printing
Printers with small bed sizes will do fine (for bed areas below 15x15 cm please contact me first to obtain adequate files set on order)
No special tools are needed during assembly (I use metal nail file for finishing places where excessive material remained)
The model's dimensions after assembly are: 370x134x72 mm (14.57x5.28x2.83 in)
If you like to experiment with this model on other track scales, the factors to match them are:
x0,847 for 32 mm track (scale "0")
x1.19 for 45 mm track (scale "G") - please note that after this scaling the minimal bed size will be 18x18 cm
(scaling factors may slightly differ depending on each printer accuracy level)

This locomotive is a bit too long in my opinion, therefore I recommend the shorter variant for use with "Euroreprap Railroad System"
