Question 1

What is the PTW1 rail scale used for?

Accepted Answer

The PTW1 is a portable rail weighing system used to capture train weight information without committing to a permanent fixed installation. It is suited to freight terminals, industrial rail sites, temporary weighing campaigns, and other operations that need practical access to train, wagon, axle, and wheel data.

Question 2

Can the PTW1 weigh trains in motion?

Accepted Answer

Yes. The PTW1 is designed for low-speed in-motion weighing for train speeds up to about 3 mph (5 kph). For faster traffic, unique site conditions, or special accuracy requirements, Walz should review the application before a final recommendation is made.

Question 3

How long does installation take?

Accepted Answer

Installation can be completed in under 15 minutes in suitable site conditions. Real deployment time still depends on track access, crew readiness, workflow, and the exact rail environment, but the system is designed specifically for very fast setup and removal.

Question 4

Does the PTW1 require cutting, drilling, welding, or foundations?

Accepted Answer

No permanent civil work is typically required. The PTW platform is a non-intrusive solution that does not require cutting, drilling, welding, or foundations, which is a major reason it is attractive for temporary projects and rail sites that cannot justify permanent modifications.

Question 5

Will the PTW1 work with different rail profiles and track gauges?

Accepted Answer

It is designed to be compatible with a wide range of track gauges and rail profiles, and the heavy-duty PTW format is intended to fit between rail fastenings. We still verify the exact rail section, fastening layout, gauge, and site conditions during quoting so the delivered configuration matches the track you actually operate.

Question 6

What capacity can the PTW1 handle?

Accepted Answer

The PTW platform is generally rated for capacity up to 40,000 kg per axle, with 20,000 kg per wheel. Other capacities are available depending on application. If your rail vehicles or loading patterns fall outside that envelope, Walz should review the project requirements before final sizing.

Question 7

What accuracy should I expect from the PTW1?

Accepted Answer

The PTW offers achievable accuracy in the +_2-3% range or better, subject to site conditions. Actual results depend on factors such as train handling, rail condition, installation quality, speed control, and the broader operating environment.

Question 8

What measurement detail can the PTW1 provide?

Accepted Answer

The system is intended to do more than produce a total train weight. With the appropriate software and indicator interfaces, the PTW workflow can support wagon, axle, and wheel-level reporting, along with setup-dependent outputs such as imbalance review, CSV exports, and print-friendly summaries.

Question 9

Can the PTW1 run on battery power, and is rental available?

Accepted Answer

Yes, the PTW platform offers battery and mains power options. Rental of the PTW is also available from Walz Scale, including installation and setup services. Walz Scale can help determine the right power and deployment model for your site, whether you need a short-term rental program or a purchased system.
