Vermont Rail System is essentially the modern day version of the Rutland.
As I mentioned before, the Vermont Railroad, as it was originally known, originally got the Rutland's main line from Burlington down to Rutland and then on to Bennington.
In 1997, Vermont Railroad bought out the Green Mountain Railroad. Green Mountain, formed in 1964, had the Rutland line from Rutland down southeast through Chester to Bellows Falls.
In 2002, Vermont Rail System, as it had renamed itself, acquired the far west end of the Rutland, from Ogdensburg, NY, 31 miles east to Norwood, NY.
That's basically all the Rutland trackage that still exists, all operating under one roof.
Other than that, they bought out the Clarendon & Pittsford, a one mile railroad owned by Vermont Marble Company, which was a major customer and interchange partner with the Rutland, in 1972.
They also bought out the D&H's Rutland Branch in 1982. That line went east from Whitehall, NY to an interchange at Rutland, VT. The D&H decided to sell the line, the same time they were abandoning chunks of the Washington Branch and selling off the rest of the Washington Branch as well as the entire Greenwich & Johnsonville. The Rutland Branch was placed under the Clarendon & Pittsford's purview by Vermont Rail System.
In 1999 they took over ex-B&M trackage from Montpelier to Barre from New England Central, as well as the joint ex-B&M/CV line from Newport north to White River Junction from Iron Road Railways in 2002. These two lines were placed under the control of new subsidiary Washington County Railroad, with the Montpelier-Barre line as the Granite District and Newport-White River Junction as the Connecticut River Division.
And then in 2022 VRS took over the old B&M White River Division between Concord & Lincoln, keeping the New England Southern name, which has been used since 1982.
