Provision is made for the operation of 21 pens, which aredistributed in three rows. The first row contains four datumpens and the second row contains the pens for registering the dis-tance, integrator records, drawbar pull, speed, throttle position,curves, indicator cards, reverse lever position, coal fired, mileposts and the time. The last row contains the pens for steampressure, train line pressure, iirake cylinder pressure, buffing forceand horsepower. A correction of S-j in. must be allowed betweenthe second and la^t rows o
