I thought that it had more to do with axle loading then total engine weight. How ever I must be wrong. The G-5s had a driving axle weight of 59.333 pounds per driver axle compared to the K-4's weight of 67,266 ppda. Total combined engine weight for a G-5 with the 110P85 tender is 449,723#. Total weight for the K-4 (with same tender capicity) is 521,621# or a differance of +71,898# for the K-4. Now, what messed up my theory is that the E-6 has 68,000# pda.
So, it must be total engine weight the LIRR was concerned about. Even though two G-5s may have been doubleheaded prior to the bridge upgrade, would both G-5s ocupy the bridge span together. If so, then the total engine weight theory also goes out the door. If only one will fit then it must have been total engine weight as the deciding factor.
