Because, looking from the north, the lines from Manhattan and from the Bronx haven't merged yet. In addition, there probably isn't room for 7 tracks and 4 platforms on a single level.Looking from the north, it is quite similar to West 4th Street (also looking from the north), just with one less track from the Bronx. |

One answer is that having it on two levels allows southbound trains to be held in a station instead of in a tunnel if they have to wait for another train to pass before merging. That's always preferable for passengers. |

The Concourse line approaches from the east and the 155th St station is on 8th Av (Frederick Douglas Blvd) which is around 100 feet lower than St. Nicholas Av (that is the topography of Manhattan for you). It was easier to build a station below the one at St. Nicholas Av that to build ramps up to an already crowded street. Once leaving 145 St the upper level ramps downward (as does the street) and the lower level ramps upward to meet around 140 St.The upper level station opened Sept. 10, 1932 and the lowerabout 10 months later on July 1, 1933 Note: I have been there (on the street) at 155 St and Frederick Douglass Blvd and there is a looooong steeeep staircase going up to St. Nicholas. There is a vehicle/pedestrian bridge to from the Bronx to St. Nicholas Av (the Bronx side is about level with the St. Nicholas side. Frederick Douglas/8 Av is way below that bridge. I'd say do a google map to look at that area to understand that area. |

Are you sure abut that turnout on the upper level is a true bellmouth for an extension to the bronx or just an oddity of construction? The reason that 145th St is on 2 levels like that is because at that point the topography of the west side of Manhattan rises into what is known as Washington HEIGHTS whereas the east side of Manhattan at that point is virtually at water level so the subway to the Bronx had to be at a level where it would be easier to access a river tube. Any ramp to the Bronx would be so far up that any sort of grade would be too steep to make such a connection possible. |

At the north end of the 145 St station, the upper and lower levels are further apart vertically than at the southern end, because the upper level continues to rise with the terrain above going north while the lower level starts to sink down to turn east to eventually go under the river. The next stop after the lower level of 145 St is 155 St - 8 Ave, which is close to sea level, in contrast to the 155 St station way up on Sugar Hill. And the two 155 St stations are tiled completely differently, even though they opened less that a year apart: Upper (no stripe):  Lower:

For some reason it seems that the local stations on the first portion of the IND are lacking the stripes. The only local station on the original IND to have a stripe is Spring St. |

It seems that the station design concept was not completely developed when the first stations were built. Two of the stations on the original line had no platform color at all, 175 St and 207 St (they both should have been in the red family, from 168 St). There were no stripes, and, because of the island platforms, there were no station-name mosaics:   (In the above image from 1970, the relatively new R40 is being used on the A line without A signs. Note that even though the ugly additional hardware has been installed on the front end, the EXP sign is still active.)) 175 St still looks like that, but after its 1990s renovation, 207 St did receive a non-standard red stripe:

Also, that would involve some serious up and down crossing over for transferring passengers, as opposed to the more or less direct up/down as exists here and at W4.And the issue of building a 7-track wide station probably also had a lot to do with it. |
