Among other markings on the side of Strasburg 7312's cab is "30%." I think this was related to valve timing in a discussion here a while back, but I can't find the thread. If it's valve timing, what, exactly does that mean? If not, what is the meaning? Thanks |

Canadian National used % as a shorthand to indicate a steam locomotive's tractive effort. 30% = 30,000 pounds tractive effort. I hope this helps! Steve Hunter Cardinal, Ontario |

30% x 1000lbs. tractive effort=30,000lbs. |
