This infobox is mainly for rail transit systems. For a specific service within a rail system, or for a rail system with only one route,  may be a better choice. For railway lines, please use  instead. For transit bus-only systems, consider using .  ব্যবহারবিধি {{Infobox public transit | box_width                   =  | name                        =  | image                       =  | alt                         =  | imagesize                   =  | caption                     =  | image2                      =  | alt2                        =  | imagesize2                  =  | caption2                    =  | image3                      =  | alt3                        =  | imagesize3                  =  | caption3                    =  | native_name                 = <!-- use {{lang}} --> | owner                       =  | area served                 =  | locale                      =  | transit_type                =  | lines                       =  | line_number                 =  | start                       =  | end                         = | stations                    = <!-- or | stops = --> | daily_ridership             =  | annual_ridership            =  | chief_executive             = <!-- or | key_people = --> | headquarters                =  | website                     =  | began_operation             =  | operation_will_start        =  | ended_operation             = | operator                    = | marks                       = | host                        = | character                   =  | stock                       = | vehicles                    = | train_length                =  | headway                     =  | system_length               = <!-- {{convert|0|mi|km|abbr=on}} --> | notrack                     = | track_gauge                 = <!-- {{Track gauge|sg|allk=on}} --> | ogauge                      = <!-- {{Track gauge|sg|allk=on}} --> | minimum_radius_of_curvature = <!-- {{convert|0|ft|0|in|mm|0}} --> | el                          = | average_speed               = <!-- {{convert|0|mph|km/h|abbr=on}} --> | top_speed                   = <!-- {{convert|0|mph|km/h|abbr=on}} --> | map                         = | map_name                    = | map_state                   = <!-- show or collapsed --> }}  পরামিতি  Parameter  Required  Description box_width  No  Width of infobox, default:22em; Note: use auto for automatic width name  No  Name of transit system; default: PAGENAME image  No  Filename of image for the header (typically a logo, but photo can be used if no logo is available) alt  No  Description of image for those who cannot see it (see alt text). imagesize  No  Size of image defined above; default:200px caption  No  Caption for the first image image2  No  Filename of second image for the header (allows for use of a picture if the logo was used for the first image parameter) alt2  No  Description of image for those who cannot see it. imagesize2  No  Size of second image defined above; default:200px caption2  No  Caption for the first image or both image3  No  Filename of third image for the header alt3  No  Description of third for those who cannot see it. imagesize3  No  Size of third image defined above; default:200px caption3  No  Caption for the third image (or all three) native_name  No  Name of the system in its native language (the place's official languages(s)) owner  No  Owner of transit system (if different than operator; if publicly owned, list that and its stock ticker) area served  No   locale  Yes  City or region transit system is located transit_type  Yes  Type of transit system.

Increase the box_width parameter, or putting auto will solve this problem.   নজরকারী বিষয়শ্রেণী      টেমপ্লেটউপাত্ত
