Great running GG1. No horn. Add a Lionel Diesel Horn shed. Very smooth running engine. Great 5 (Gold) stripes against Brunswick Green. Doubled motor. Has more than enough power. If you don't want all the fancy TMCC Legacy electronics and would like to own a great running GG1 consider the K-line brand. This is my only K-line engine. I'm very pleased with the GG1. Prices are very reasonable.
