Signalling

"Streamlined involves the use of many different signals which the player can choose to follow." - Streamlined Tutorial

Overview
Along streamlined's tracks stand multiple posts, boards, signs and other constructions. These, like their real life counterparts, tell information to people on and next to the tracks. In-game, most of these are placed for realism and details, though some affect gameplay.

Signals
Railway semaphore signals (or "armseinen" in Dutch) are scattered along the rails. Albeit mostly for realism, signals provide a bonus if followed. Signals are shown on the map as a green, yellow or red circle, corresponding with their current position. A signal's front is coloured red whereas the backside is white with black stripes. In areas with poor visibility, such as sharp corners, signal warning boards are placed alongside the rails to warn players on upcoming signals.

Signal bonus
If a player follows all signals, they can earn a 25% bonus on top of the route's base money. The amount the boost is worth is calculated like this, simplified for easier understanding:

$$Signal Bonus=BasicReward*((SignalsFollowed/TotalSignals)*0.25)$$$$BasicReward + SignalBonus + StoppingAccuracyBonus = FinalReward$$

In-game, doing a route with 10 signals and failing 5 would mean:

$$SignalBonus = BasicReward*(5/10)*0.25) $$ Which would result in earning an extra 12,5% (totalling to 112,5% total) rewards. Despite this, following signals is not required, just encouraged.

Generic signal
The most common signal in Streamlined. Green means go, red means stop.

Warning signal
The warning signal is usually placed below a generic signal and have a yellow position instead of a red one. They show what the next generic signal's position is. A green warning signal means the next signal on this track is green. A yellow warning signal means the next signal is red and that it may be smart to slow down.

Generic + Warning signal
Most commonly, warning signals are placed below a generic signal. This combination of the two is an efficient way to tell the player whether the tracks up until the next signal are clear and what the current position of the next signal is.

Double generic signal
Signal posts like this are generic signals for two neighbouring tracks. The lower signal is for the closest track, the higher signal is for the track further away.

In the picture, this means the left signal is for the left track, but this may not always be the case.

Signal bridges
These are at most large stations. Similar to a double generic signal, they provide a signal for multiple tracks. It is much easier to know which one is yours, as the signals are directly above the track they manage. They can have generic, warning and generic + warning signals mounted and don't always have a signal for each track.

Known issues
Developers know the current signal system can break, an overhaul is planned


 * Signals sometimes remain red for several minutes
 * Signals sometimes remain red until a train nearly goes past them



Speed signs
All rails in Streamlined have a maximum speed. There's no punishment for not following it as it's in the game for realism. The game currently has two ways to indicate the maximum speed.

The first are speed limit signs are placed along the rails. These are recognisable as a small, white square with black edges and a black number. To figure out how fast you can go, multiply the number by 10.

Besides these signs, the game shows the current maximum speed with a red indicator on the speedometer.

Whistle sign
These signs, with an appearance similar to speed limit signs, are in the game for detail and realism purposes. The large 'F' on them stands for 'Fluit', which is Dutch for 'Whistle'.

Railway crossing signs
These signs, used both with and without barriers, inform people who wish to from A to B how many tracks are in their way.

Loading gauge measuring
The loading gauge constructions are placed in various shunting yards in Streamlined. They signal how high and wide engines, wagons and coaches can be to prevent collisions with platforms, bridges or other trains passing by. Because all of those in Streamlined are made with the gauge in mind, they're only in the game for decoration.
