Scope
1. To design safe railroad crossings that maximizes the movement of people and goods.
2. Design safe pedestrian crossing across the railroad tracks.
3. To design effective intersection closures that minimizes the impact on traffic and the community.

Background• The City of Rainier is on the south bank of the Columbia River across
from Longview, Washington.
• This project is part of the Rainier Waterfront Urban Renewal Plan.
• The closing of the Trojan nuclear power plant set off a decline in the number of businesses in the city.
• The current population is around 2,000 people.
• Freight trains with 110 railcars pass through downtown Rainier along A Street.
• On average there are 4 trains per week traveling in either direction
5
Project Overview• Project consisted of:
– Design closing for 3 crossings– Redesign 4 crossings
• The City of Rainier has no dedicated engineering staff.– Lars Gare, City Administrator
• ODOT Rail has final design approval– Dave Lanning, Crossing Safety/Compliance

Traffic Conditions

Peak Volume < 300 vph Operating well below capacity Does not require signals No additional studies needed
7 Crashes in past 11 years 0 Crashes involving rail Most crashes related to parking or backing All crashes during daylight hours
Crash History

Time Intersection Collision Type Cause Severity Weather Conditions
11 AM 2nd St W Parking No Yield PDO Clear Dry
11 AM 1st St Backing Too Fast Injury "C" Cloudy Wet
9 AM 1st St Parking Other PDO Clear Dry
1 PM 2nd St E Parking Other PDO Clear Dry
12 PM 2nd St E Backing No Yield PDO Rain Wet
4 PM 3rd St E Turning Other PDO Clear Dry
2 PM 3rd St E Rear End Too Close PDO Clear Dry
• Increased frequency of trains moving through Rainier
• Increased train size and time to move the train through A Street
• Railroad being partitioned off by curbs and removal of the asphalt from the railroad tracks
Future Conditions

ODOT’s One to One Offer to City
• City of Rainier Responsibilities– Select at-grade crossing to close, ODOT will pay for
the closure and upgrade one intersection– Must produce all design & engineering plans– City is financially responsible for 1 of the 4 upgrades
• ODOT Rail– Maintains final design approval– Will finance and construct 3 crossing closures and 3
crossing upgrades
• Future Closures– City decided due to usage and location that it would be beneficial to
close the following
• 2nd Street East
• 4th Street East
• 5th Street East
• Future Gated/Controlled– City decided that it would be necessary to allow the following
intersection to remain open however to provide control measures for safety purposes.
• 2nd Street West
• 1st Street
• 3rd Street East
• 6th Street East

Construction Recommendations
• Construct crossings in conjunction with railroad improvements
• Leave all crossings opened during construction
• Closure of the three intersections final phase of construction
• Identify delivery and train schedules to work construction around them
Design Considerations
• Space limitations, including all necessary safety measures while still leaving space for future improvements.
• Minimizing impact on traffic and businesses

Some sort of project conclusion here…
“Lessons Learned” – what would we have done differently?
Prepare a schedule at the beginning of the project including all key dates
Better accountability of group members
Better communication between our group and our contact
