■ 1. 概述

在路線和列車文件中，您經常會遇到整數或浮點數之類的數字，有時還會遇到其他數字。這些編號必須遵循某種格式，以下將對此進行介紹。

數字有兩種解析方法：嚴格 和 寬鬆 。嚴格方法不會留有犯印刷錯誤的空間。所有新文件格式均使用此方法。寬鬆方法是與舊方式兼容所必需的傳統解析模型。在 為OpenBVE進行開發 頁面上顯示的不同文件表示正在使用哪種模型。請注意，只要允許 寬鬆 模型，您也可以使用 嚴格 格式，因為 嚴格 構成 寬鬆 的子集。

■ 2. 整數

嚴格: 允許的任何序列至少為一個小數點，範圍為0到9(U+0030 - U+0039)，並可以帶一個負號(U+002D)。結果字符序列可能包含前導或尾隨空白。

寬鬆: 首先從字符序列中刪除所有空格。然後，根據 嚴格 模型解釋其餘字符序列(abcde)。如果此操作無法創建有效數字，則從序列(abcd)中刪除最後一個字符，然後再次測試該序列。這一直持續到產生有效數字或直到沒有剩餘字符為止，此後字符序列被確定為無效數字。

■ 3. 浮點數

Strict: Permitted is any sequence of at least one decimal digit in the range from 0 to 9 (U+0030 - U+0039), optionally interleaved by exactly one decimal separator in form of the period (U+002E), optionally prepended by a negative sign (U+002D). The resulting character sequence may include leading or trailing white spaces.

■ 4. Times

Legacy: Permitted is any of the following sequences:

In these sequences, hhh denotes any sequence of at least one decimal digit to indicate the hour, mm denotes the two-digit minute part, m denotes a one-digit minute part, ss denotes a two-digit second part, s denotes a one-digit second part, and the character to separate the hours from the minutes is the period (U+002E). All digits need to be characters from 0 to 9 (U+0030 - U+0039). Leading or trailing white spaces are ignored. The total time is determined via the following formula, resulting in seconds since midnight:

If minutes or seconds are not indicated, they are assumed to be zero. You can use any non-negative hour, including values greater than or equal to 24. If, for example, a station arrival time is 23:59:00 (day 1), and the arrival time of the following station is 00:02:15 (day 2), then use the following sequences to represent these times in order to ensure a chronological order:

■ 5. Color values

Hexcolor: A six-digit hexadecimal number is preceded by a number sign character (U+0023). An individual hexadecimal digit can be comprised of the decimal digits from 0 to 9 (U+0030 - U+0039), the lowercase letters from a to f (U+0061 - U+0066) and the uppercase letters from A to F (U+0041 - U+0046).The hexcolor has the following form:

In this sequence, RR represents the red component, GG the green component and BB the blue component. Each component ranges from 00 to FF (0 - 255), where 00 represents no contribution for that channel and FF full contribution.

Commonly used colors (to indicate transparency) include:
