Source-derived summary

The EMD GP10 is a diesel-electric locomotive that is the result of rebuilding a GP7, GP9 or GP18.

The Illinois Central Railroad had three separate rebuild programs to upgrade their old EMD GPs and GPs that they had purchased from equipment dealers such as Precision National Corporation in Mount Vernon, Illinois. The first was the GP8, second the GP10 and third the GP11. All were rebuilt at IC/ICG's Paducah Shops in Kentucky.

Core units for the GP10 program were from IC/ICG GP7, GP8, GP9 and GP18, B&M GP9, B&O GP9, CRR GP9, C&O GP7 and GP9, D&RGW GP9, DT&I GP7 and GP9, FEC GP9, GTW GP18, P&LE GP7, Potlach Forests Inc. GP7, QNS&L GP9, RDG GP7, St.J&LC GP9, SLSF GP7, SP GP9, SSW GP7, and UP GP9B.

Two IC GP9s were rebuilt to GP10s and sold directly to the Ashley, Drew and Northern Railway. Nine Alaska Railroad GP7s were rebuilt to GP10s by Paducah, and renumbered 1801-1809 (these rebuilds received EMD angled cabs but kept their AAR Type B road trucks from Alco RS-1s).

A total of 76 Conrail GP9s were rebuilt to GP10s. The Paducah Shops rebuilt 53 Conrail GP9s to GP10s. The first 16 Conrail GP9s were rebuilt to the equivalent of a GP10 in 1976.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1801, 1809, 1976—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with GP10, rebuilt and locomotive providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “EMD GP10”, the useful work is to connect “rebuilt locomotive class” to the records capable of establishing context and consequence.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 3, 2026. The linked authority identifier is Q3045965. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1801, 1809 and 1976.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
