Parallel Systems is on a mission to build an autonomous, zero-emissions rail cars. To bring them to market, the team needs test infrastructure that scales with the fleet, not against it. Here's why Parallel chose Sift.

MISSION
Moving short-haul freight off trucks and onto rail
BUILDING
Autonomous, electric, zero-emissions rail vehicles that carry standard shipping containers
Parallel Systems builds autonomous, battery-electric rail vehicles that carry standard shipping containers on existing rail networks. The dream is to cut emissions by moving short-haul freight off of trucks. With Federal Railroad Administration approval, a commercial pilot launched in 2025, and $100M in funding, Parallel is scaling toward a fleet.
Autonomous rail earns its place by proof. Parallel must show regulators and customers that its vehicles meet or exceed the safety standard of conventional freight rail, a detailed body of evidence built from analysis, testing, and demonstration. That takes enormous volumes of vehicle telemetry, and none of it can be thrown away.
Parallel's in-house telemetry stack worked at ten engineers and one vehicle, then scale broke it: ballooning storage costs, a slow UI, manual reporting, and engineers scaling databases instead of building machines. Rather than rebuild it themselves, Parallel moved everything to Sift and put every engineering hour back on the vehicle.

Parallel's open-source telemetry system was built for a small team and a single vehicle. As operations scaled, storage grew untenable, data review slowed, and reporting stayed manual. Multiple engineers were diverted to keep the pipeline running and cutting data storage was never an option.

Keep every signal without ballooning cloud bills, flag anomalies across the fleet automatically, and generate automatic reports for your team, customers, and regulators, all in Sift.

Parallel cut infrastructure costs 85%, saves >$140k in engineering costs per year, and returns 150+ hours per engineer per year on data review. Per-vehicle analysis takes minutes, and the body of evidence for regulators builds faster with every test.
In their words
With so much riding on these machines, every engineer diverted to fixing our dated telemetry system feels like lost momentum. We needed a modern solution to help move us forward.

85%
Reduction in infrastructure costs
Sift's storage infrastructure replaced a system that grew more expensive with every vehicle, and search got faster at the same time.
>$140k
Engineering cost savings per year
The engineers who were scaling databases and chipping away at pipeline feature requests now build vehicles.
150+ hrs
Saved per engineer per year on data review
Reviews that crawled through a dated UI now run through Sift's data review workflow, with long-term views on every aspect of the vehicle.
Minutes
Time to per-vehicle analysis
Detailed, long-term analysis of any vehicle in the fleet, ready in minutes instead of hours of manual assembly.
Sift for Transportation
Parallel generates enormous volumes of vehicle telemetry they can't afford to lose. On Sift's storage infrastructure, they shrank their infrastructure costs by 85% and sped up search, keeping every signal they need for testing while retaining only what matters long term. With Sift, Parallel generates all the data it wants and still pulls longitudinal insights across vehicles, without ballooning cloud bills.
Parallel analyzes vehicle behavior across a growing fleet, not just one railcar. On Sift, the team automatically flags issues and anomalies, running detailed, long-term analysis of each vehicle in minutes. Parallel scales toward hundreds of vehicles while keeping the safety bar that autonomous freight rail demands.
Parallel's engineers must prove to regulators and customers that autonomous rail meets or exceeds conventional freight safety. With Sift, they automate the entire process from data review through report generation, dropping the cumbersome manual reporting in common business tools and tailoring each report to its audience. Parallel builds its body of evidence faster, on one timeline from test to ops.
