What is it with EMD’s format of numbering their locomotive models? In other words, Why did they follow the SD90 with another variant of the SD70 (SD70ACe), which is really a different locomotive, and not name it the “SD100” or something? Will EMD release an eventual SD100 or SD110, etc?
Also, does EMD no longer produce GP-model locomotives?
The current SD70ACe is a follow-on locomotive in the ‘70’ line of engines. The SD80 used a 20 cylinder 710, and the SD90 used the 265 H power plant. EMD & GE have not produced a 4 axle road switcher for a number of years now(the EMD GP60 and GE Dash-9 B40 have not been produced for years).
EMD’s naming convention has been gradually ‘increasing’ for years. GE seems to ‘re-arrange’ their naming convention every few years - Just marketing…
EMD would produce new GP model 4 axle locomotives if customers wanted to buy them, but as has been discussed extensively on this forum, 6 axle units have been preferred for road power for a long time (almost 2 decades). They do rebuild older GP’s with new engines (GP22ECO)…
