Duplicating this locomotive body is not easy! It has tiny holes, sharp edges and thin walls plus no reasonable way to place the sprue and vents. We'll try it with a squish mold, but the odds are not in our favor!

This video is the first of two parts. In part two I make resin castings from this mold. Here is that video:    • Casting An HO Scale Locomotive - Part 2  

The train model 3757 is made by the Märklin Company. For more info about their products visit:

The actual train this model is based on is a BR 103 locomotive.
The footage comes from the YouTube channel Sebastián López. Check it out at:    • BR 103 113-7 Stuttgart HBF 25-11-2014
