In that year, the company was sold again, to the Cities Service Corporation, mainly once more for its associated power generating business. The line operated as part of the Ohio Public Service Company, the name the cars would bear for a further 21 years. The new company painted the cars in high-visibility "traction orange". The extension to Bay Point was abandoned in 1926. Service levels were cut to only six departures from Toledo a day from a high of fourteen as the Great Depression hit; only three of these travelled the whole line. Single-man operation was adopted to cut costs in 1932. Ridership continued to fall, until in 1938 only 48,900 passengers rode the line, down from 934,055 in the peak year of 1915.
