Railway Vision

Railways that run to your song on a real signalling system: a signal box panel whose track circuits light in each train's colour as it runs the loop, a night line of lit trains, an invented city's network map, a busy junction, a cab ride and a model railway. Trains depart on the beat, routes set on the bar, signals clear on the downbeat, the build brings more trains out and the drop lights every route at once.

Track Circuits

The signal box's illuminated panel of a double-track loop with two stations, platform loops and sidings, lit in a dim box with lamp glow and haze. Every track circuit lights in its train's colour while the train stands on it, the route ahead lights up to the first red signal, signals step from red to yellow to green behind each train and clear on the beat, the points throw on the bar and each train's four-character code steps from berth to berth. The build brings more trains out and on the drop every route lights at once.

Night Line

A railway at night seen in depth: trains of lit windows glide along a viaduct over a river and curve away into the distance, headlights cutting the haze, stopping at a lamp-lit station on the beat. The lineside signals change from green to red behind each train and back, the track lights in each train's colour where it runs, the town's lights and the stars answer the highs and on the drop the whole line lights at once.

Classic Studio

Network Map

An invented city's railway map, four lines of its own colours: every stretch between two stations lights while a train runs it, stations ring as trains call, trains slide along the lines with their codes, and the next route lights ahead of each one. The build adds trains to every line and on the drop the whole network lights.

Classic Studio

Junction

A close view of a busy flat junction at night: the branch leaves the main line and crosses it on a diamond, the points throw on the bar, the home signals clear on the downbeat with their route lights for the branch, long trains cross over under the floodlights and the track lights in each train's colour as it runs.

Classic Studio

Cab Ride

The view from the driver's cab at night: rails running to the horizon, signals and track circuit markers rushing past on the beat, the route set ahead lit in the highlight colour up to the next red signal, platforms and junctions sweeping by, trains passing the other way, and the cab's display showing the train's code, its speed and the next signal.

Classic Studio

Model Railway

A model railway on a table in a warm room, seen from three quarters: trains loop through a tunnel and two stations, signals change aspect on the layout, points throw on the bar, the lit control panel at the front shows every track circuit, and on the drop every lamp on the layout comes on at once.
