UP has a large yard at Spring which is primarily used for storage and they also have a facility for unloading autoracks that is easily visible from the toll road. Just north of Spring, the track splits with one line going north to Conroe, Trinity, Crockett and Palestine. The western leg goes to Navasota, north to Bryan on the former SP, then to Valley Jct. It is a very busy line. Traffic has increased since the UP merger with BNSF now also having tracking rights on this line to the north.
Traffic is moderate.
New BNSF service to New Orleans goes north to Cleveland on this track before moving east on their own rails. BNSF also has tracking rights on this line to Memphis. It continues northeast of the map to a bridge across Lake Houston and then swing east to Beaumont. There is no easy chasing in the immediate Houston area. Traffic is moderate.
