There was a 4000hp single engine diesel locomotive built 3 years before the M640. It was the HS4000 'Kestrel' in the UK, from 1968. Being of British manufacture but with a Sulzer engine developed in Switzerland I'm not sure if the hp figure was in Imperial hp or Metric hp. Also it's not clear if the power of both the M640's and/or Kestrel's engine was given in gross power (engine power without auxilaries like water and oil pumps, cooling fans etc.) or the newer SAE net power (measured with all auxilaries connected to the engine as delivered) as 1971 was around the time conversion to the net power figure took place in automotive industry. Metric or DIN hp is always net hp measured at the cranckshaft. So it's difficult to say that Alco's M640 really was the worlds most powerful single engine diesel locomotive at the time, or that she was preceded by and even with Kestrel. There was also a 4000hp single engine diesel locomotive that entered service in Belgium in 1971, #5001, but like the M640 both Kestrel and #5001 were prototypes without series build following. #5001 featured the V16TR 240CO engine by Cockerill in Belgium, which was a licence holder for LHB (Lima-Hamilton-Baldwin), and constructed many engines of the Baldwin 608A model and also from a Hamilton design for Belgian locomotives, the new V16 had design features derived from the 608A engine, but never was used again for rail traction but for marine use.

I think Alsthom-Atlantique had a near-4000 HP unit on the SNCF, with a Piestik in it

Locomotives did not fall under SAE standards for automobile and light truck applications in North America. Locomotives in North America are rated by their available horsepower for traction, but it is the work they can do that matters the most, and that is traction effort, which equates to its tonnage rating, or how much the until can pull on any given subdivision. The 4000 hp of the 4744 is rather insignificant compared to its tonnage rating of 6000 tons - which seems low, but hard to say what subdivision that rating is for. On a relatively flat line segment, it's probably somewhat higher than the SD45, and about on par with the U36C (shared electrical systems and governors). Out in the mountains, EMD didn't really offer anything at the time that could pull like the big Alco or GE.

4744 wasn't just another 4000HP locomotive, it was a test bed for AC traction technology far ahead of its time. With AC traction it could easily out-pull any standard locomotive even with the same engine power.

I heard this thing had some serious vibration problems with the engine, whatever that means. Of course, the whole thing went down when CP messed with her systems and caused the damn crankshaft to tear off (or so I’ve been told).

From what I heard, it suffered a serious crankshaft failure while working on the D&H in 1992. No replacement part could be found, so it ended up at Exporail in St-Catherines, QC, in 1998, after sitting in the deadline for 6 years, never to turn another revenue wheel.

Wasn't the 4744 the first AC locomotive? It was 6,000 hp at one point before being downgraded again.
