The use of electric lighting was further made possible because the Central London was also the first tube railway to use AC electrical distribution and the substation transformers were easily able to provide convenient voltages to run the lighting.
Brugen af elektrisk belysning blev yderligere gjort mulig, da Central London også var den første tube-bane til at bruge vekselstrømsforsyning og transformatore på fordelingsstationer kunne nemt skaffe belejlige spændinger til at drive belysningen.
