Jacob Pneumatic (or simply Jacob), is an electric transit engine. Jacob Pneumatic was purchased by the F.& F. R. W. T. Co. Ltd and converted to work on Celgreb City Transit Railway taking passengers around Celgreb City. While he works hard, he can be a little pompous about being the only engine to run the special line, and tends to be a little arrogant. Despite being a bit self-entitled, he will work hard to get passengers to the stations on time, and it does take a lot to get under his motor.
