The negative results were found from testing the most commonly touched areas at stations such as ticket machines, door handles and toilet flush buttons – regularly used staff areas including drivers cabs and messrooms were also tested.
After the swab test samples were taken, they were analysed in a laboratory to allow the operator to react quickly to any positive results and conduct a thorough deep clean.
The swabbing project is part of a detailed plan EMR has put in place so passengers can travel with confidence.
Other steps taken include it employing the most cleaners in its history, sourcing powerful disinfectant products and purchasing new specialist fogging cleaning equipment.
Neil Grabham, customer services director at EMR, said: “Quite rightly passengers expect that we are doing everything possible when it comes to cleanliness.
"These negative results are a testament to the hard work our cleaning colleagues have been doing to keep our trains and stations safe but also reflects the dedicated efforts of our staff to follow rules and work in a covid-secure way.
“The swabbing project is just one part of our new enhanced cleaning measures that we have put in place to make sure passengers can feel confident when they return to our network and we intend to maintain it as the country slowly moves out of lockdown.”
Tests were carried out at Nottingham, Sheffield, London, Derby and Leicester stations.
