BOTH have advantages. Locomotives are powered by electric traction motors because electric motors can generate more torque. Locomotives get the electrical power generation to the electric traction motor from 4500 hp diesel engines. In essence, these are hybrids, and have been for over SEVENTY years and counting. Both types of power are needed for pulling the amount tonnage the railroads needed. The latest locos carry 5300 gallons of diesel fuel to generate the electricity to drive these monstrous electrical motors which move and astronomical number and amount of supplies across the country, from consumer goods to raw materials, to large artillery, and even large air and space elements. The railroad still is a very efficient means of bulk transportation.
Today's electric motors are much improved - my model trains are running digital compared to my old ones in the 1960's, 70's and can run much smoother due to nanotechnology and improved windings. Again, the engines still need a source of electrification to drive the motors. The issue today is finding a good, effective, reliable energy sources to produce electrification. We take for granted the number of capacitors (over 700 in your cell phone), which is commonly used to store short bursts of electricity. Your car radio clock and radio settings store all information and time using capacitors when the engine is off, as do many electrical and electronic devices we use everyday. Same for your pc to store data in memory while your pc is not in use or asleep when not plugged up and the battery runs down (or more importantly). Capacitors have improved, and these are always in high demand worldwide to the point where even before the pandemic supply was very tight, and everyone wants more fancy appliances everywhere in the home for washing, sweeping, lighting, doorbells, and trickling down to lawn care products, using bluetooth. Commercially, I don't see contractors using electrical tethered tools as much as I used to, opting for the battery versions for which brushless motors have added battery life, improved torque, and even reduced weight significantly. The Saturn EV1 in the 1990's, while with its mere range of 75 miles with conventional batteries, was still a beast to drive with its high torque motors. These dedicated electric vehicles with electric motors and tranny's need fewer parts compared to conventional gas/diesels. I have been driving electric golf carts for at least 50 years with no issues.
Bottom line - I love both electric motors and diesel engines, but I want quick, simpler sources to drive the electrics. At the same time, I want the benefit of fewer, simpler things to work on (not a Tier 4 EPA gasper with a multitude of electronics and valves manipulating fuel/air/exhaust input/output). I am not even discussing the political side of it - not going there - only comparing the benefits and downsides of each energy/drive based on where we are at today. Life is tough.
