A steam locomotive

A study of a steam locomotive with three visible driving wheels, connecting rods, and a cylindrical boiler on textured paper. Build the boiler cylinder and cab box above a shared wheel baseline.

A way into the drawing

1. Establish the construction

   Build the boiler cylinder and cab box above a shared wheel baseline.

2. Resolve the main structure

   Place three near driving wheels and connect them with a coherent side rod.

3. Develop the detail

   Add the chimney, front face, buffers and selected piping.

4. Control the values

   Group the black metal masses and reserve narrow highlights on curved surfaces.

A small thing to tryAlign the driving-wheel axles before drawing the connecting rod.
