Tomball consultant outlines FRA quiet‑zone process; council opts to pause active pursuit
Summary
A consultant briefed Tomball council on the Federal Railroad Administration's quiet‑zone process, potential safety measures and multi‑million‑dollar costs; after questions about ownership, safety data and funding, council reached an informal consensus to pause active pursuit and asked staff to prioritize repairs at local crossing approaches.
Frank Twinavides, a multimodal engineer with Ardura Group, told the Tomball City Council on Oct. 6 that establishing a railroad quiet zone is a federally regulated, multi‑step process administered by the Federal Railroad Administration under 49 CFR part 222.
Twinavides said a quiet zone requires a minimum half‑mile segment of rail where horns are not routinely sounded and that cities must perform a diagnostic review with police, fire, TxDOT and rail operators before submitting a notice of intent to FRA. He described supplemental safety measures — such as median islands and four‑quadrant gates — intended to prevent vehicles from going around gates and said those measures are reviewed by FRA before a notice of establishment is submitted.
"So what are quiet zones? ... they're designated sections of a rail line where train horns are not routinely sounded," Twinavides said during his presentation, noting the regulatory citation "49 CFR part 222." He estimated the full process (diagnostic review, design approvals, construction and FRA review) could take roughly five years and said costs vary widely by crossing and measures required; he cited a planning figure of up to $2,000,000 per crossing in a worst‑case scenario.
Councilmembers probed local specifics. Staff said the city controls three crossings (including the Houston/Central and Main Street crossings and Zion), while Harris County and other entities own others. Staff also said BNSF averages about three trains per day through town. Twinavides acknowledged historical research linking earlier unregulated horn suppression to increased crossing incidents but said he did not have immediate fatality counts and offered to follow up with data.
Members raised practical concerns: steep crossing approaches created during upgrades can lead to vehicles bottoming out, and some crossings are county‑owned — raising questions about who would pay for improvements and insurance. One councilmember questioned why a city would take on potential additional liability; others pointed to public requests for quieter crossings and examples from other Texas cities that have pursued quiet zones.
After discussion, staff recommended pausing active pursuit of a formal quiet‑zone application while the city coordinates further with railroad partners and county agencies. Council reached an informal consensus to put the formal quiet‑zone effort on hold but asked staff to pursue maintenance work on the crossing approaches ("launching pads") and to continue coordination with BNSF and other partners.
No formal vote was taken. Staff said they would report back with further study, potential diagnostic findings and any additional cost estimates or funding options should the council decide to resume the quiet‑zone process.
