The engines (and peripherals, notably the cooling radiators) used on mainline diesels in North America are big enough that a hood covering them comes too close to the top of the loading gauge to allow much higher cabs. The Cat 3512 is a smaller, higher r.p.m., engine than the GE 7FDL-12 originally used on these units. (Note that the power has been reduced to 1550 kw: the units were originally built as something over 2200 kw.) So this rebuild is perhaps comparable to the "genset" switcher/local freight units built in the past decade or so, using small-bore, high-speed, diesels. (Some have been built on the frames, and with the trucks and fuel tanks, of GE Dash-7 4-axle units.) These have lower engine hoods than mainline units, and have cabs that are significantly higher than the hoods.

The cabs aren't much higher than American standard, look at the C36-7i behind it for comparison.
