Rapido Manufacturer Description & Prototype History

Introducing the complete Phase III GE 4-axle Dash-7 collection from Rapido! It’s a mess, and that is how GE made it. In late 1976, GE introduced the Dash-7 line, which consisted of dozens of internal updates to its Universal series model range. The most obvious external changes are that all Dash-7 models have a wider section of the hood ahead of the radiators, and feature protruding wings for the radiator section.

Like the C36-7, other changes to the 4-axle Dash-7 were made incrementally. The six-axle Dash-7’s always retained the same wheelbase, while the four-axle models feature not one, but three wheelbases identified in three phases which apply to each model.

In production by GE from 1977-1984,

• B23-7: GE 12-cylinder FDL diesel engine rated at 2250 HP
• B30-7: GE 16-cylinder FDL diesel engine rated at 3000 HP
• B30-7A/AB: GE 12-cylinder FDL diesel engine rated at 3000 HP
• B36-7: GE 7FDL 16-cylinder diesel engine rated at 3600, 3700 or later 3750 HP

Identifying phase features of the B23-7 and B30-7:

Phase I:

• Overall length of 62’ 2”, and truck centers of 36’2 2”.
• These truck centers are the same as the predecessor universal models, but those had a shorter overall frame.

Phase II

• Same 62’ 2” overall length but change to wider truck centers of 37’ 2” by shifting the rear truck backwards, eliminating the space between the stepwell and truck at the rear.

Phase III

• Our Dash-7 series in this release covers the Phase III models.
• Overall length is a foot shorter – 61’ 2”
• Truck centers 36’ 8”. Visually, this gives the appearance of the trucks being balanced and centered, without major gaps at the end.

Phase III design features begin in 1981, and additional orders for B23-7’s (MP, NdeM, Southern, Santa Fe and B30-7’s (Chessie/C&O) were built with the revised design features. ATSF, MP, and Southern units are defined most by their road-specific order details.
