T Corp LLC seeks variances for garden railroad and trestles on 55‑acre Rhinebeck estate

T Corp LLC on March 19 presented plans to the Town of Rhinebeck Zoning Board of Appeals for a multi‑phase garden railroad and related site work on a 55.096‑acre estate on the west side of River Road and requested five area variances for structures associated with that plan.

Seth Stickel, representing T Corp LLC, and Mark Reminski, P.E., described a phased project including multiple loops of a 1:8 scale train, trestle spans, a roundhouse and car barn, a conservatory and a covered arrival platform. They told the board parts of the development are already under construction and that earlier approvals covered southern and central loops. “This parcel is 55.096 acres,” Stickel said while tracing the unusual flag‑lot configuration and describing ingress from Teahouse Lane and River Road.

The variances the applicant requested include two height variances for trestle/bridge spans (a maximum trestle height proposed at about 29.3 feet, requesting roughly a 9.3‑foot variance where 20 feet is the limit; and a signature bridge with towers and truss with a maximum height of about 51.6 feet, requesting roughly a 31.6‑foot variance). The application also seeks relief because the aggregate area of accessory structures on the parcel would total about 16,731 square feet — approximately 202 square feet over the 16,529 square feet calculated under the town’s accessory‑structure formula (300 sq. ft. per acre × 55 acres). Two additional variances would allow the covered platform and the glass conservatory for the garden‑scale train to be located in front of the principal dwelling rather than behind it; the principal dwelling sits about 2,918 feet back from River Road while the covered platform and conservatory locations were shown at roughly 1,078 feet and 965 feet from River Road, respectively.

The board discussed wetlands and permitting. The applicants said New York State Department of Environmental Conservation jurisdictional wetlands review has been submitted and that the DEC has up to 90 days to respond; a portion of the proposed trestle was designed to span an intermittent drainage to avoid direct wetland impacts. The applicant said they plan to crane in certain bridge spans to avoid ground disturbance in the drainage corridor and that historic aerials show the proposed conservatory/loop area was previously developed as the Carmelita Sisters site.

The board voted to accept the application and set the matter for a public hearing; the application was also referred to the planning board, which will consider site‑plan special permits and serve as the lead agency on environmental and wetland matters. Seth Stickel said the team hopes to begin foundation work for the signature bridge this year and complete the bulk of construction through 2026 with finishing work into 2027.

Why it matters: the proposal includes nonstandard accessory structures and tall trestles in a residential zoning district, wetlands and buffer impacts that require state and local jurisdictional determinations, and aggregate accessory area calculations that are slightly above the local allowance; each of those items is the subject of the variances the board must evaluate.
