Plotting geojson data

The dataset contained data points with numerous labels which I wanted to plot. First I had to manually process the data point labels because the labels were not uniform, for example ​'Bridge (road over rail)','Bridge (rail over road)','Rail Bridge','Railway Bridge' and so on. Once I had identified all the labels I was interested in I collected them in lists and used these to create dataframes which were subsets of the main dataframe:

station = ['Station','Railway Station','Station Facilities','Station & Goods Store','Railway Station, Goods Shed, Milepost & Bridge, Comber Junction','Ballyclare Junction - Ballyboley Junction','Cookstown Junction']
df_station = df_places[df_places['X_TYPE'].isin(station)]

viaduct = ('Viaduct','Railway Viaduct')
df_viaduct = df_places[df_places['X_TYPE'].isin(viaduct)]

bridge = ('Bridge (road over rail)','Bridge (rail over road)','Rail Bridge','Railway Bridge','Road crosses railway (bridge ?)','Road Bridge (over railway)','Bridge (ra/ro)','Road above railway (bridge ?)','Bridge ?  Railway above road','Level Crossing & Bridge')
df_bridge = df_places[df_places['X_TYPE'].isin(bridge)]

other = ('Turntable','Signal Post','Ballynahinch Junction','Signal Box')
df_other = df_places[df_places['X_TYPE'].isin(other)]

level_c = ('Level Crossing','Level Crossing & Milepost','Road crosses Railway','Milepost at Level Crossing','Milepost & Level Crossing','Milepost & Crossing')
df_level_c = df_places[df_places['X_TYPE'].isin(level_c)]

Then I plotted this data onto a blank outline map:

ax = df_map.plot(color='blue', alpha=0.4)
df_station.plot(ax=ax,color='yellow')
df_viaduct.plot(ax=ax,color='red')
df_bridge.plot(ax=ax,color='orange')
df_other.plot(ax=ax,color='green')
df_level_c.plot(ax=ax,color='purple');

This generates the following:
