Engineers who have completed electrical courses might be needed if plans to remodel Bank London Underground station go ahead.
Richard Parry, the transport network's strategy and commercial director, pointed out that the hub currently suffers from severe congestion at certain points in the day.
The proposals could be put into action by 2015, with work potentially carried out by workers with professional training - such as electrical courses - aiming to complete the initiative by 2021.
"If this work is not carried out station control measures, such as restricting access at busy times and non-stopping trains, would have to be implemented even more frequently," Mr Parry said.
According to the news provider, the station is currently used by about 300,000 passengers each day, with this figure having risen by 43 per cent in recent years.
Transport for London claimed there has been a seven per cent shift over the past year in the number of people using public transport, cycling and walking instead of driving.
