Frequently Asked Questions

Is this plan official?

No. This is a citizen-proposal, which means it was proposed by citizens of Salt Lake City who want to influence future decisions by state and city leaders.

What about the water table?

Ground water is a real concern that many projects in Salt Lake City have dealt with in various ways. For instance, the underground parking garages for the Gateway shopping center – which are located immediately east of the proposed Rio Grande Plan ‘train box’ – use a mix of sealants and sump pumps to keep their parking areas dry. Similar solutions can be applied to the proposed ‘train box’ to ensure that tracks are always kept clear and dry.

Where does Union Pacific Railroad stand in relation to this plan?

Union Pacific Railroad has not yet made any public comment on the Rio Grande Plan. Obviously, the success of the plan is highly dependent on their cooperation. The Rio Grande Plan is based heavily on projects which Union Pacific partnered on, such as the ReTRAK project in Reno, NV, and the sale of the Burnham rail yards in Denver, CO. The dimensions and grades of the Rio Grande Plan’s ‘train box’ were all designed to meet Union Pacific’s standards, and further refinements can be made to suit the railroad’s needs.

Ultimately, we believe this project will be a net positive for all parties involved, including Union Pacific Railroad. The closure of 4 railroad crossings will mean fewer accidents, fewer delays, fewer trespassers, and less maintenance costs. We do not believe any organization should be coerced into a project that it does not find beneficial, and we will continue to make modifications to the Rio Grande Plan until all affected parties can agree to participate.

What about diesel fumes and emissions?

There is no question that the train box below 500 West will require ventilation of some kind. Though electrification of UTA’s commuter rail system is anticipated in the future, at present UTA, Union Pacific, Amtrak, and other rail service providers operate exclusively with diesel locomotives. The emissions of these locomotives will need to be vented in one of two ways.

The first alternative is a passive ventilation option, which would require a series of ventilation shafts to be constructed in a raised median along 500 West. The second alternative is an active ventilation system, which would see large fans mounted on the ceiling of the train box to push exhaust gases down the length of the covered portion.  Most likely is that a combination of these techniques will be used to ensure that the train box is filled with fresh air,  and that the neighborhoods on either side of 500 West are not impacted.

The total length of the covered portion of the train box will be approximately 1 mile in length, which is shorter than many railroad tunnels currently in operation in the United States. The mechanics of providing clean are into tunnels is well understood, and should be incorporated into the design of the train box from the beginning.

Won’t the grades of the railroad tracks be too steep?

The Rio Grande Plan was designed from the beginning to allow for generous grades into and out of the train box below 500 West. The maximum grade for Union Pacific tracks was limited to 1%, or 1 foot up per 100 feet forward. The maximum grade for UTA tracks is 2.5%.

Both of these grades satisfy their respective railroad’s design criteria. Grades will not be an issue in the implementation of the Rio Grande Plan.

On the north end, it is anticipated that the UTA tracks will reach surface level immediately south of the North Temple Bridge station, while the Union Pacific tracks will take until just south of the 300 North crossing to fully reach the surface. On the west end, the Union Pacific connector track will reach surface by 900 West. 800 West street will closed at the railroad crossing, but will be diverted to a new east-west alignment below Interstate-15 at 50 South. On the south end, there are no constraints, and the ramp may continue as long as necessary.

What about the Green Space on 500 West by the Gateway?

The Rio Grande Plan seeks to improve the infrastructure of every neighborhood it touches, and the green space west of the Gateway is no different. At present, the former rail ROW west of the Gateway is preserved as a grassy median with large trees. This area will unfortunately need to be excavated for the construction of the new train box, but this disruption also presents an opportunity in what is put back when construction is finished.

Because of the railroad tracks needing to ‘ramp up’ to surface level at this location, the median of 500 West will need to be raised no more than 9 feet on the north end (the south end will not need to be raised at all). This will create a unique opportunity for landscaping, such as grass, water features, raised planters, and potted trees. The raised nature of the park can be utilized to create a railroad viewing area, following the pattern of other ‘railfan parks’ across the country.

Ultimately, the design of this area will be up to city and neighborhood leaders to agree upon. So while a change in the area will be required in order to accommodate the Rio Grande Plan, careful planning and coordination can ensure that all changes can be positive.
