The Pennsylvania A3 Switcher: The First Project for the Beginner

The Pennsylvania A3 Switcher is a 264 page hardcover. The construction project in 3/4” scale (that you may scale up to 1 1/2” scale) is perfect for the first time builder. Sharp, detailed photos, incredibly illustrative drawings and inch dimensioning appeal to expert builders as well. Very thorough descriptions of part fabrication make any novice machinist able to build the engine with ease and confidence, from stock materials.
