Thank you, Richard, and good morning, everyone. We will cover our prepared remarks first, followed by Q&A. Before I cover the normal detailed information, I would like to provide an overview of key drivers of our second quarter results because the numbers alone do not match where we think we are headed operationally or versus some of our peer results, and I'm sure that interests each of you. During the quarter, we shutdown our second largest facility in Texarkana and sold another facility in Dallas, Texas, and consolidated most of our non maintenance-related personnel in Chattanooga and Greeneville, Tennessee. This was a significant operational, HR, and IT lift, similar to an acquisition since the SRT business in Texarkana had been operated primarily as an autonomous solo refrigerated service offering.
We downsized our fleet by 262 tractors and repositioned a portion of the remaining tractors between segments, which involved an intermediate -- immediate revenue loss with some ongoing expenses due to unpaid miles and a tail on fixed overhead, specifically depreciation.
Our dedicated operations experienced volatility due to a concentration in automotive and automotive supplier business that were shutdown for a significant portion of the quarter as well as certain contracts that do not require a minimum load count or payment so that we had to put trucks to work elsewhere.
The freight environment for the quarter was very weak in April and progressively improved. The sum of the above is that we pushed a lot of disruption and expense into a relatively weak freight quarter. The table in our operating press release -- the table in our press release, quantifies approximately $29.3 million of infrequent items, including net gains and losses on asset sales and impairments, certain shutdown and severance costs, but it does not capture all the related operational costs or revenue drop off and a tail on our fixed expenses.
For the third and fourth quarters, we expect some ongoing operational and restructuring costs, but not at the level of the second quarter. While our fixed cost overhead continued to come down and the freight environment continues to improve materially versus the first two quarters.
The sales pipeline is robust across our truckload and managed freight segments. Our team is focused on taking steps required over the remainder of the year to exit this year to be best prepared for 2021.
Turning to more detailed results. Notable financial results for the quarter included: Our Highway Services Truckload segment's revenue, excluding fuel, decreased 7% to $73.3 million due primarily to an 8.8% average operating fleet reduction, partially offset by a 2% increase in average freight revenue per tractor in the 2020 period as compared to the 2019 period. Versus the year ago period, average freight revenue per total mile was down $0.126 or 6.7%, while average miles per tractor were up 9.3%. The main factors impacting the increased utilization were 1,180 basis point increase in the percentage of our highway services fleet comprised of team driven tractors at an improved average seated tractor percentage, as only 3.7% of our Highway services operational tractor fleet lacked drivers, compared with 6.9% during the prior year quarter.
The longer average length of haul related to the higher percentage of team driven tractors contributed to the reduced average rate per total mile. Our dedicated truckload segment's revenue, excluding fuel, decreased 16.6% or $60.4 million, primarily due to the combination of the pandemic related second quarter automotive shutdowns at 2 large customers and an 8.6% average operating fleet reduction. Versus the year ago, dedicated average freight revenue per total mile increased 11.6% -- $0.116 or 6.4%, while average miles per tractor were down 14.3%. Excluding the impact of the truckload related restructurings on the second quarter and the second quarter 2020 adjustments, total operating expenses, net of fuel surcharge revenue increased $0.074 cents per mile compared with the year ago period for our combined truckload segment. This is very attributable to the higher per mile driver wages, non-driver wages and casualty insurance costs, basically offset by lower workers' compensation and maintenance and repair costs.
Our managed freight segment's operating revenue increased 10.6% versus the quarter -- year ago quarter to $45.9 million. This increase was driven by a 40.3% increase in freight brokerage operating revenue and operating revenue to $28.4 million, partially offset by 17.9% decrease in the combined operating revenue of TMS and warehousing. Managed freight operating loss was $2.9 million for an operating ratio of 106.4.
As a result of the second quarter decision to sell the assets of Transport Financial Solutions, the related results are presented as discontinued operations. This presentation has all activity net of tax into a single line item, income from discontinued operations net of tax. TFS' results net of tax provided $0.05 per share of earnings in the second quarter of 2020 and 2019, respectively.
We recognized $0.5 million of pretax income from our 49% equity method investment in TEL compared with pretax income of $2.4 million in the second quarter of 2019, as TEL returned to profitability in the second quarter following reported losses in the previous 2 quarters.
The average age of our tractor fleet continues to be young at 1.8 years as of the end of the quarter, down from 2.2 years a year ago.
During the first half of 2020, we took delivery of 305 new tractors and 155 new trailers while disposing of 781 used tractors and 219 used trailers. We reduced our operational fleet size by 398 tractors or 13.2% to 2,623 tractors by the end of June from our reported operational fleet size of 3,021 tractors at the end of December. In the second half of 2020, we expect an average operational fleet size of approximately 2,550 tractors which we expect to allow us to maximize the utilization of our fleet, including an improved mix of more consistently profitable freight. Between March 31, 2020 and June 30, 2020, total indebtedness net of cash, decreased by $52.4 million to $284.4 million. This sequential decrease to net indebtedness included net cash proceeds from the sale of real estate and excess revenue equipment.
At June 30, 2020, we had cash and cash equivalents totaling $67.1 million as well as available borrowing capacity of $58.3 million under our asset-based revolving credit facility for a total of $125.4 million of liquidity. The sole financial covenant under our ABL facility is a fixed charge coverage ratio that is tested only when available borrowing capacity is below a certain threshold. Based on our availability as of June 30, no testing was required, and we do not expect testing to be required for the foreseeable future. With this color, I will turn the call over to Joey for a recap of a few additional items.
