How to divide a train track for a partial electrification?

Hi, I’m updating the information about the electrification of the of one of the lines in my country, but the problem is that the train track is divided in the station, not outside, so I can’t update accurately.

For more details, the electrification is in the Roca Line in Argentina, from the Bosques station up to the Juan María Gutierrez station. I can’t find were exactly will end the electrification, but it at least should cover one track of all the Gutierrez Station.

Here is the Gutierrez station
