Final repairs to the tracks and signalling equipment is ongoing, with this work expected to complete early tomorrow morning, a spokesperson said.
Matt Rice, route director for Network Rail’s north and east route, said: “We’d like to thank everybody for their patience whilst we’ve worked to clear the area and carry out repairs to enable a full service to resume once more.
“Fewer people are travelling on the railway because of the four-week lockdown.
“However, we know that people do still need to make essential journeys and this incident has impacted on them.
“We’re very grateful for their patience during this time and we’re glad that from tomorrow, a full train service is planned and you’ll be able to travel as normal once more.”
