Between 1854 and 1929
, The Orphan Train Movement carried about 250,000 homeless children by train from places such as Boston and New York  City to   other states within the United States as well as Canada. The  trains were not always a luxury, depending on the time in which they  were ridden.  The very first  trains were nothing more than  cattle cars with  some  seats and a  bathroom. However, as more money  was available
, the  trains  got better and the children were able to ride  in Pullman cars, which were basically sleeping cars.
 A big reason for the Orphan Train Movement was due to the number of    immigrants that entered the United States between 1841 and 1860.   These  people came to the United States and worked in jobs that didn’t pay a  lot. They also lived in houses that housed ten other people.  Since the  living conditions were poor
, this led  to diseases spreading and as a result  many  parents died prematurely.   Also, orphanages were built to house  as many children as possible and  parents could pay for the care on a  weekly or monthly schedule. If they  did not pay on time the children ended up   becoming a ward of the  court and that left social workers to  dispose  of  the children as they  felt was best. All these factors led to about 30,000 homeless children  in New York.
 The person that started the Orphan Train Movement was Charles Loring    Brace. He was a Presbyterian minister who came to New York City   to  proselytize the poor. Brace wanted to reach out to the young  because he  felt they   could be converted a lot easier than the older  generation.  His early   outreach consisted of Boys Meetings  during  which the young  boys received food and Bible  instruction.  However, Brace soon realized that this wasn’t really  helping and that  more  needed to be done. The solution that he came up  with was that these  children needed to be  put  to work. He stated that  “There is no doubt  that a lad with a trade   feels a peculiar  independence of the world, and  is much less likely  to  take up  dishonest means of living.” [

 There was a lot of debate about the Orphan Train Movement. The     movement initially took place prior to the Civil War and a lot of  abolitionists were upset about this movement because a number of the  children were not being placed in houses where they were cared for but  were instead being indentured. In a nutshell they  were not being   adopted  but were being used solely for labor which was  viewed as an   extension of  slavery. While the demand for children was  based a lot on   the need for  labor, the Children’s Aid Society still did  what they  could to make sure  that the children were treated well.   If a  family  wanted to take a  child they had to be endorsed by a  committee  of  local business owners,  doctors and journalists.  Some  of the terms   included things like the  children needing to be sent to  school and the   Children’s Aid Society  would check on each child once a  year. The   children were also expected to  write a letter to the society  twice a  year. However, when the children  would get off the trains to find  families    they would be inspected like  animals such as having their  teeth  checked   as well as their muscles  which was very dehumanizing.
 There were a lot of hardships associated with the movement and most of     them were considered emotional. For example, one person recounted how   his new ‘family’ did not speak the language and so their own son had to   interpret for them. The son took advantage of this barrier and   made  the  indentured boy responsible for all of the chores. The boy    recounted  how  he did not feel as though he fit in. There are other   stories of  children  being separated from their siblings and not being   sure of  their own  origin. However, not all the children had bad   experiences.  Some were  taken in and felt loved and have a great   respect for their  adopted  family. An example of this comes from  Stanley Cornell who was placed on a farm. He was expected to work rather  hard but he was clothed, fed and loved by the family. He has always  been grateful for what they did for him. 
 The Orphan Train Movement came to a close in 1929 due to a number of    different road blocks but one of the biggest was due to all the state  legislature that had been passed to forbid the transport  of children  across state lines. However, the success of the Orphan Trains as  well  as other Children’s Aid initiatives ended up  leading to a  number  of  different child welfare reforms. Some of these  included child  labor   laws, adoption and the establishment of foster  care, public  education   and some provisions for healthcare, school  lunches and   vocational  training.
