A PDF guide to building a cc781905-5cde-3194-bb3b-136bad5cf58d model of the British 4900 Hall Class Tank Locomotive. 259 of these locomotives were built between 1924 and 1943. These universal locomotives were used for both passenger and freight services. The "Olton Hall" locomotive with train number 5972, the film locomotive from the Harry Potter films, attracted particular attention. According to the book, the locomotive was repainted in a red color.
  
 The finished model of the locomotive is 66 knobs long and 10 knobs wide and consists of about 1087 individual parts. It can be powered by a Power Functions L motor. The IR receiver and the battery box can easily be accommodated in the large tender. The model is equipped with numerous details such as pipes, chassis or the detailed driver's cab. This article is the green version.
  
 The model was specially developed for the 3D printing wheels available here. The matching 3D printed connecting rods are available here .
