Five tools. One research base.

Twenty-five years of passenger behaviour research have given rise to a whole family of software products. TrainOptimizer® is the flagship product for rail passenger transport. MetroOptimizer, TramOptimizer and BusOptimizer apply the same methodology to smaller transport systems — with a more streamlined feature set, but the same quality and accuracy. TrainDesigner complements the family with a tool that allows vehicle layouts to be sketched out in minutes.

About Us

Real data.
Real results.

netwiss OG is a Vienna-based research and consulting company dedicated to the efficiency of passenger vehicle interiors. For over 25 years, in partnership with TU Wien's Research Centre for Railway Engineering, we have built Europe's most comprehensive dataset on how passengers actually move, sit, and store luggage — across 10+ countries and 300+ vehicles.

No approximations. No theoretical models. Only real passengers in real vehicles.

Why it matters

Why vehicle layout matters

Luggage storage

Before

Racks stay empty while aisles fill up

  • Racks are sized for neither the size nor type of real luggage
  • Passengers avoid racks they cannot reach, lift into or see from their seat
  • Bags end up in aisles, at seats and in doorways instead
After

100% stowable luggage

  • 100% of luggage can be stowed
  • No safety risk from incorrectly placed luggage
  • Shorter dwell time
  • No restrictions for on-board staff
  • Higher passenger comfort

Dwell time

Before

Every bad layout decision extends the dwell time

  • Poor overall layout
  • Too much focus on maximum seat count
  • Insufficient luggage storage
  • Poorly positioned doors
  • Restricted passenger flow
After

Up to 70% shorter dwell time

  • Up to 70% reduction in dwell time
  • Higher punctuality
  • Faster boarding and deboarding
  • Lower energy demand to keep the timetable
  • Better operational reliability

Capacity and seat usability

Before

Installed seats are not the same as usable seats

  • Seats blocked by luggage
  • Capacity reduced by poor storage concepts
  • Passenger comfort drops
  • Effective occupancy is lower than planned
  • Standing and movement areas become less usable
After

100% usable seats, up to 20% more capacity

  • 100% of seats remain available
  • Capacity can increase by up to 20%
  • Higher achievable occupancy
  • Better passenger comfort
  • More realistic planning for real operations

Operations, energy and cost

Before

Small layout problems become expensive

  • Delays and lower punctuality
  • Higher energy demand to recover time
  • Lower average speeds
  • Longer turnaround times
  • More vehicles and staff may be required
After

Lower cost, lower energy, better service

  • Up to 20% energy savings at the same timetable
  • Fewer vehicle rotations needed for the same service
  • Lower vehicle and personnel costs
  • Significant cost and energy savings
  • Higher customer satisfaction

TransportOptimizer tools simulate and benchmark these effects before decisions are locked in, comparing layouts by luggage stowage, seat usability, total capacity and dwell time.

Before you ask

Questions we get from every serious buyer.

Yes. The methodology is built on 25+ years of research by netwiss in cooperation with TU Wien, 400,000+ passengers observed and 60,000+ surveys across 10+ European countries — and it has already been applied to real fleets including ICE3, Railjet and ETR610.
