2-2-2013: Updated version. The skip body is more stable op the supports/chassis preventing unwanted tiping of the skip during travel.
5 H0e tippers modelled after the Spoorijzer KW13 1m3. This version has Roco / Minitrains / Egger-Bahn compatible couplings. For the exact version see here
The model is designed to been used with these axles. But any H0e axle ~14mm wide and with a flange no larger than 7.6mm in diameter will do. Some examples are the Sehling RDS4.3-SH0e wheels, Metal Wheels from Nigel Lawton or Roco / Fleischmann 20024.
