Maasai women will on Monday petition President Uhuru Kenyatta against SGR being routed through Nairobi National Park.
Organisers said women from Oloosirkon, Kitenkela, Emakoko and Embakasi villages will present their plea at Harambee House.
The group, dressed in traditional Maasai regalia, will converge at Uhuru Park at 9am before they match to the President's office.
The women will later head to KWS headquarters where they will stage a sit in.
The government has continued with public hearings on the SGR despite an environmental tribunal barring activities over the same.
The tribunal ruled that matters SGR be stopped until the case filed over the project is heard and determined.

"The processions are not against infrastructure projects. We don't want those that are poorly thought out, environmentally unsound and abuse our natural heritage like having SGR pass through the park," Nkamuno Patita, one of the organisers, said.
"Our call to the President is to have the phase two of the SGR rerouted away from the our conservation areas. So far, Nairobi Park has had enough of assault and allowing SGR through it will be one way of declaring its death," she added.
