Over on HistoricBridges.org, I call these modified Warrens because while they appear similar to Baltimore truss bridges, they use Warren config for the primary diagonals as opposed to the Pratt. A Baltimore is by definition a variation of a Pratt.
I don't know what the general consensus is here on BridgeHunter for this type. There was a discussion about weird truss types a while back:
This through truss in San Bernardino county is an unusual design, to me, and it needs a better design description. All assistance and education appreciated.
