Three major railways' smooth commuter services for dwellers of the capital city and its vicinity in Argentina did not stagger amid months of strict lockdown, thanks to hands-on support provided by a multinational tech team. The lockdown which has come into force since March has brought challenges to many of the essential workers who relied on public transport for commuting across Buenos Aires. However, these measures did not impede the operation of the Roca, Mitre and Sarmiento electric railway lines, which link the capital Buenos Aires respectively with its south, west and north outlying areas.
