This data set is a linear depiction of railway mainline rights of way. Included are the active rail lines as well as the abandoned lines. Each separately owned mainline route is depicted as a single line--multiple tracks, sidings, yards, and industrial spurs are not shown.

PCC Lines are shown by rail line segments. This feature class was built using existing data sources including railroad line track charts, track right-of-way maps, and recently digitized linework based off aerial photos.

These files are an extract of selected geographic and cartographic information from the 1995 TIGER/Line files detailing railroads. This dataset includes railroad tracks, railroad main lines, railroad spurs, railroad yards, railroad ferry crossings, car lines, and cog railroads.

Historic rail line locations throughout Pierce County sourced from Washington State Archive and Bureau of Land Management historic maps dated from 1850's to 2010.

This is an extract from the State Highway Log that shows Railroad Crossings that are at the same grade as the state route. State Route identifiers and locations based on State Route Mileposts and Accumulated Route Mileage are also included for geographic reference and for use with the Washington State Department of Transportation's 24k and 500k Linear Referencing Systems. Please direct questions about this dataset to: TransportationGISDataSteward@wsdot.wa.gov. Other notes: RRXingGradeInd attribute definition does not include detail about what the code values mean.

Rail stations along the PCC rail line. These are not passenger train stations, but are locations where freight is loaded onto or unloaded off railroad trains. Stations were placed using latitude and longitude coordinates.

PCC Lines are shown by major branch lines. This data is used as 1) a linear referencing system (LRS); 2) for locating features on the PCC system by milepost value. PCC lines were built using existing data sources including railroad line track charts, track right-of-way maps, and recently digitized linework based off aeiral photos. In LRS, the locations of both data and events are determined according to their distance along a railroad line from some known point (e.g., the beginning of the line or line segment, a mile marker, a junction with another rail line, or a railroad crossing).

This georectified digital map portrays geologic formations and mineral lands near the Northern Pacific Railroad in Northern Idaho and Washington Territories in 1882. The original paper map was scanned, georeferenced, and rectified to broaden access and to facilitate use in GIS software.

This map service provides general bridge information for all transportation structures within the Washington State Bridge Inventory System (WSBIS) in Washington State. This includes bridges, large culverts, tunnels, pedestrian & railroads passing over state routes, and pedestrian bridges adjacent to state routes on state right of way. The accuracy and completeness of the transportation structure data (including the structure location) are the responsibility of the structure owner. In cases where pedestrian & railroad structures pass over state or local agency routes, this data may be the responsibility of the route owner under the structure. Note that local agencies do not include a complete inventory of pedestrian & railroad structures in local agency rights of way. Please Note: If there is a vertical clearance restriction related to the bridge/structure, the minimum clearance will appear in either the MinVertClrncOverDeck, MinVertClrncUnderBridge or TunnelMinVertClrncOverRdBy10 fields.

The Washington State Department of Transportation (WSDOT) developed this data set in fulfillment of a grant from the Federal Highway Administration (FHWA) to test a conceptual climate risk assessment model developed for transportation infrastructure. WSDOT applied the model using scenario planning in a series of statewide workshops, using local experts, to create qualitative assessment of climate vulnerability on its assets in each region and mode across Washington. For the purposes of this statewide effort, managed assets were defined as sections of highway or railroad, and whole facilities (Ferry Terminal or Airport). Fourteen workshops engaged experts across all WSDOT regions, state ferries, rail, and aviation. The outcome of each workshop was a subjective evaluation of asset vulnerability agreed upon by participants. This feature class contains the results for railroads. This study assumed 100% probability of climate change impacts previously identified in the University of Washington Climate Impacts Group's 2009 assessment. Types of impacts discussed in the workshops with local experts included: temperature changes, increase in extreme weather events, precipitation changes, sea level rise, fire risk, and high winds. The scientific community's understanding of climate impacts continues to evolve as the models and collective understanding of feedback systems improve. We do not have perfect information about exactly how, when, where, and to what magnitude climate changes will unfold in Washington State. After reviewing the extreme weather events and other impacts projected for their area, workshop participants defined sections of highway, rail, or specific facilities with consideration of the local geology, natural and constructed drainage and hydrology, elevation, slope, land use and operational maintenance issues. Once defined, each corridor or facility was then ranked for two variables: asset criticality and potential impact. Asset criticality (which was defined by the workshop participants) should not be confused with other measures such as highway functional class. 1) How critical is that site or corridor to overall transportation operations and public safety? The following scale guided the qualitative assessment of criticality: a. 1-3 = Low - facility/corridor with low daily traffic, available alternate routes, not part of the National Highway System b. 4-6 = Medium - facility/corridor has low to medium daily traffic, serves as an alternate route of other state corridors or facilities c. 7-10 = High - facility/corridor is an Interstate or other major highway, is considered a lifeline route or is the sole access to a population center or critical facility. 2) How might potential climate changes impact site or corridor operations? The following scale guided the assessment of climate impacts: a. 1-3 = Low - Reduced Capacity: facility/corridor partially open to use and full operations can be restored within 10 days b. 4-6 = Medium - Temporary Operational Failure: Facility/corridor closed for hours or days. Reopening or repair could be completed within 60 days. c. 7-10 = High - Complete Failure: facility/corridor likely to require major repair or rebuild with closures lasting more than 60 days These qualitative rankings for impacts and asset criticality and some general descriptions were captured in spreadsheets that were later used to create GIS layers. This data is intended for use in statewide or regional planning and to assist in adapting maintenance and engineering policies and practices to protect our transportation infrastructure over the coming decades. The rankings here were based on our knowledge and understanding at the time of the study, and should only be taken as a best professional estimate for considering potential conditions that might put people or infrastructure at risk. Current information about projected climate changes and asset use and condition should always be taken into account, especially as time progresses.

This policy aims to promote a system in which sustainable land use and transport are mutually compatible. The objectives of this policy are to: protect people from unreasonable levels of transport noise by establishing a standardised set of criteria to be used in the assessment of proposals; protect major transport corridors and freight operations from incompatible urban encroachment; encourage best-practice design and construction standards for new development proposals and new or redeveloped transport infrastructure proposals; facilitate the development and operation of an efficient freight network; and facilitate the strategic co-location of freight handling facilities. The purpose of the implementation guidelines is to assist users with the application and implementation of the Western Australian Planning Commission’s state planning policy 5.4. It should be noted that the policy and these guidelines apply to proposals for new noise-sensitive developments, new railways or major roads, major redevelopments of existing railways or major roads, and new freight handling facilities. The policy and guidelines do not apply to noise from existing railways or major roads in the vicinity of an existing noise-sensitive land use, or an increase in traffic along an existing railway or major road in the absence of a major redevelopment. It is expected that a review of the operation and effectiveness of the policy would be conducted within two years of the commencement of the policy.

PCC Lines are shown by major branch lines. This data is used as 1) a linear referencing system (LRS); 2) for locating features on the PCC system by milepost value. PCC lines were built using existing data sources including railroad line track charts, track right-of-way maps, and recently digitized linework based off aeiral photos. In LRS, the locations of both data and events are determined according to their distance along a railroad line from some known point (e.g., the beginning of the line or line segment, a mile marker, a junction with another rail line, or a railroad crossing).

The Forest Practices Abandoned Roads (ROPA.FPTRANS_ABANDONED_RDS) data layer, an ArcSDE read-only data layer, represents only officially abandoned and orphaned roads existing within the state of Washington. All active roads are now updated and maintained in the DNR's Proprietary Roads (ROPA.ROADS) data layer. The original data layer, TRANS_ROAD_RTE_SV, which originally joined the TRANS spatial data to both the TRANS_ROAD table (road characteristics) using the TRANS_ARC_NO field, and to the TRANS_RTE table using the TRANS_RTE_REF_NO field, has now been split into two data layers. One data layer (ROPA.FPTRANS_ABANDONED_RDS) consists of all abandoned and orphaned roads; the other (ROPA.FPTRANS_OTHER_RTS) consists of trails, railroads, railroad grades, and ferry crossings.Roads abandoned using the official Forest Practices approval process and Roads Orphaned prior to 1975ROPA.FPTRANS_ABANDONED_RDS OBJECTID Internal feature number.
