Baltimore & Ohio

Lord and Lady Baltimore

The Baltimore & Ohio is certainly not shy about experimenting with motive power, as evidence these two one-of-a-kind creations. Above we see the "Lord Baltimore": an early 4-6-4 fitted with a water tube boiler (standard locomotive boilers are fire tube types). Notable features of this design include a bit of European styled streamlining and an enclosed cab.

While the "Lord Baltimore" can turn in some impressive performance figures, the water tube boiler has proven unsuccessful (it can be noted that water tube boilers have been tried by many roads, but with little useful results).

Below we see another interesting experimental, the "Lady Baltimore". This is a rare "Jubilee" type 4-4-4 (of which not more than 3 or 4 have been built for North American service). Keeping with the fashion of the hour, this locomotive also features European styling and enclosed cab.

The concept here was to create a heavy duty Atlantic type similar to the Pennsylvania Railroad E6s. (Note that the forward part of the power train looks remarkably like the PRR locomotive.) The generally beefed up design was extended out and a 4 wheel trailing truck added to carry a large, free steaming firebox.

Interesting as it is, the Jubilee type never really got off the ground. With only 4 drivers, there is far too much weight on the non-productive pilot and trailing wheels. Further (and this is in common with the PRR E6s) 4 wheel power has simply been overtaken by increasing train weight and speed.

Had the Jubilee type been developed earlier- say, as an outgrowth of the Atlantic type at the turn of the century- it might have found more acceptance before eventually being overtaken by the 4-6-2s.
